The Best Underwear for Women of 2025

Underwear is the supporting actor of your outfit: if it’s great, you forget it exists; if it’s terrible, it becomes the main character in a drama called “Why Am I Thinking About My Butt Right Now?” In 2025, the “best underwear” conversation has finally matured beyond “cute vs. comfy” (as if we needed to choose). Editors are wear-testing everything from breathable cotton briefs to laser-cut no-show thongs, while clinicians keep repeating the same evergreen advice: let the area breathe, keep moisture from hanging around, and avoid anything that rubs you the wrong way literally.

This guide pulls together what’s consistent across major U.S. testing roundups and medical guidance, then translates it into real-life picks and practical rules you can use in the dressing room (or at 2 a.m. during an online-cart spiral). No awkward product pushing, no pretending one style works for every bodyjust the stuff that actually matters in 2025.

What “best” means in 2025

The best underwear for women in 2025 usually nails four things at once:

• Breathability: Airflow matters, especially if you’re prone to irritation, yeast infections, or just living in a humid zip code.
• Moisture management: Not just “absorbent,” but “doesn’t stay damp.” (Sweat is fine. Marinating is not.)
• Friction control: Smooth seams, soft waistbands, and fabrics that don’t saw at your inner thighs like a tiny rope.
• Outfit compatibility: No-show edges for leggings, stable coverage for dresses, and a gusset that stays put instead of migrating north.

Also new-ish (but now mainstream): inclusive sizing, better plus-size engineering (waistbands that don’t roll, leg openings that don’t pinch), and category-specific undies (workout, shapewear-lite, period backup, travel pairs).

A quick fabric cheat sheet (aka “What’s touching your skin all day?”)

Cotton (and organic cotton)

Cotton is still the gold standard for everyday breathability and sensitivity-friendly wear. If you’ve ever dealt with itching, irritation, or recurring infections, cotton underwear (or at least a cotton gusset) is the simplest upgrade you can make. The trade-off: pure cotton can feel damp if you sweat a lot, and it can show lines under clingy clothes unless the cut and seams are designed for it.

Modal / micromodal / TENCEL-like fibers

These plant-based fibers have a “cool, silky T-shirt” vibesoft, drapey, and often better at moisture feel than standard cotton. They’re popular in 2025 “everyday luxury” pairs because they’re comfy without feeling bulky. Watch for blends and a breathable gusset if you’re sensitive.

Microfiber, nylon/spandex blends

This is the land of seamless, no-show underwearthe stuff that disappears under leggings and satin skirts. High-quality versions can feel featherlight, but the wrong pair can trap heat and moisture, especially if the gusset isn’t breathable or the fit is too tight. In 2025, many of the best “invisible” options solve this by using laser-cut edges plus a cotton-lined crotch.

Lace (the “it depends” fabric)

Modern lace can be surprisingly soft and stretchy, but it’s still texture. If you’re easily irritated, lace every day may not be your love story. But for occasional wear, a high-quality stretch lace thong or brief can be comfortableespecially if the waistband and leg openings aren’t tight.

The 2025 winners: underwear types that actually earn their drawer space

1) The everyday breathable pair (your “default setting” underwear)

If you want the most universally helpful underwear category, start here. The 2025 best version usually looks like: cotton or modal body + comfortable waistband + non-binding leg openings + a gusset that stays flat.

• Best for sensitive skin: High-cotton briefs/bikinis/hipsters with a soft waistband and minimal seams.
• Best for avoiding wedgies: Hipster and boyshort cuts with enough back coverage and a leg opening that doesn’t “grab.”
• Best for hot sleepers: Breathable cotton pairs (or skipping underwear at night, if that’s comfortable for you).

Example picks that show up repeatedly in U.S. editor testing include classic cotton multipacks (budget-friendly staples), organic cotton hipsters, and upgraded “cotton with stretch” bikinis that hold shape after washing. If you hate panty lines, look for flat seams or bonded edges in a cotton-forward fabric.

2) No-show/seamless underwear (for leggings, satin, and clingy dresses)

Seamless underwear got significantly better in the last few years, and 2025 is peak “invisible but not suffocating.” Look for:

• Laser-cut edges (less ridge = fewer lines)
• Wide, gentle waistband (prevents rolling and digging)
• Cotton-lined gusset (helps with breathability even if the body is microfiber)
• Enough stretch recovery so it doesn’t sag after two hours

The common failure mode of cheap seamless underwear is “it slides around and then bunches in one spot like a tiny scrunchie.” If that’s happened to you, it’s usually a sizing and stretch-recovery issue, not your body being “wrong.” Size up if you’re between sizes, and prioritize a brand that explicitly mentions a cotton gusset and tested no-show edges.

3) Workout underwear (the anti-chafe, anti-sweat squad)

For exercise underwear in 2025, the goal is not “the cutest.” The goal is: stays put + doesn’t rub + dries fast. Great workout underwear usually features:

• Moisture-wicking fabric (often performance blends)
• Seam placement that avoids friction zones
• Stable leg openings that don’t creep up mid-squat
• Easy-care durability (because you’ll wash it a lot)

If you’re prone to irritation, consider changing out of sweaty underwear promptly after workouts. If you love thongs for movement freedom, choose a performance thong with a breathable gusset and a waistband that doesn’t dig. If you hate thongs, try a performance hipster or boyshort that stays flat under leggings.

4) “Pretty but practical” lace (special occasions without special suffering)

The best lace underwear in 2025 is soft, stretchy, and engineered to avoid the classic problems (itchy edges, digging waistbands, and lace that shows through everything). If you want lace you can actually wear:

• Look for stretch lace with a smooth waistband (often scalloped edges lie flatter).
• Avoid anything that feels “crunchy” on first touchit will not become magical after washing.
• If you’re sensitive, choose lace styles with a lined gusset and gentler leg openings.

Translation: you can have cute underwear without spending the entire evening wondering if you’re allowed to scratch.

5) Plus-size underwear that doesn’t roll or pinch

The best plus-size underwear in 2025 is designed (not just scaled up). Key signs you’re looking at a real plus-size-friendly pattern:

• Wider waistband with stable elastic (less roll-down)
• Smoother leg binding that doesn’t create a “rubber band” effect
• Back coverage that matches the front (no surprise half-cheek situation)
• Size range transparency (brands that test across sizes tend to fit better)

Many editor lists consistently recommend cotton boyshorts and high-rise briefs in extended sizes because they’re comfortable, breathable, and forgiving throughout the day (especially for sitting, bending, and commuting).

6) Period underwear and “backup pairs” (for real life, not perfect life)

Period underwear has moved from niche to normal. In 2025, a lot of women use it in one of three ways:

• Primary protection on lighter days
• Backup for tampons/cups on heavy days or long meetings
• Spotting insurance (ovulation, postpartum, peri-menopauselife has seasons)

The best approach is to keep a few dedicated pairs, follow care instructions closely (to preserve absorbency and odor control), and choose cuts that feel secureespecially at night. Breathable options matter here too, so look for reputable materials and a design that doesn’t feel like a plastic raincoat.

How to choose the right cut (without overthinking it)

If you want fewer wedgies

• Try hipsters, boyshorts, or high-rise briefs with a stable leg opening.
• Avoid super narrow bikini backs if you’re constantly “adjusting.”
• Check the back seam: if it’s thick and stiff, it’s more likely to shift as you move.

If you want fewer panty lines

• Go for laser-cut or bonded edges.
• Choose fabrics labeled no-show or seamless with a cotton gusset.
• Size up if the leg opening digstight edges create lines.

If you deal with irritation or infections

• Prioritize breathable cotton underwear or at least a cotton panel.
• Avoid tight fits that trap heat and moisture.
• Consider skipping underwear at night if it helps you feel less irritated (and if it’s comfortable for you).

Note: If you have recurring infections, persistent itching, burning, or pain, it’s worth speaking to a clinician. Underwear can help, but it can’t diagnose or treat an underlying issue.

Care and rotation: make your best underwear last

In 2025, underwear fabrics are betterbut they’re also more specialized. A few habits will extend the life of your favorites and keep them feeling clean and comfortable:

• Wash with a mild detergent and skip heavy fragrance if you’re sensitive.
• Avoid fabric softener on performance and moisture-wicking pairs (it can coat fibers and reduce function).
• Air dry delicate lace and seamless underwear when possible to preserve stretch and edge bonding.
• Retire pairs when elastic is shot, fabric is thinning, or the gusset no longer feels fresh even after washing.

A simple system: keep a small “VIP drawer” of your best daily pairs, a separate pile for workouts, and a few no-show options for specific outfits. Underwear chaos is realbut it’s also fixable in one laundry cycle.

FAQs (because underwear raises surprisingly deep questions)

Is cotton always the best underwear material?

Cotton is often the best all-around choice for breathability and sensitive skin. But if you sweat heavily, a high-quality performance blend can feel drierespecially for workouts. The most important detail is usually a breathable fit and (for many people) a cotton gusset.

Are thongs “bad” for you?

It depends on your body and your history. Some clinicians advise avoiding thongs if you’re prone to irritation or infections, because friction and close contact can be a problem for some people. Many women wear them without issues. If you love thongs, choose breathable materials, avoid overly tight fits, and switch out of sweaty pairs quickly.

How many pairs should I own?

Enough to go at least a week without laundry stress, plus a few category pairs (2–4 no-show, 2–4 workout, a couple of “nice” pairs, and period/backup if you use them). If you’re constantly doing emergency laundry for underwear… your underwear drawer is trying to tell you something.

What’s the deal with a cotton gusset?

The gusset is the crotch lining. A cotton gusset can improve comfort and breathability even when the rest of the underwear is a synthetic blend. In 2025, many top-tested seamless and performance styles highlight this feature for a reason.

Real-world experiences in 2025 (the “okay but what does it feel like?” section)

You asked for experiences, so here are the most consistent real-life patterns that show up across wear tests, editor notes, and the lived reality of women who have places to be and zero desire to spend the day thinking about their underwear.

1) The “desk day” effect is real. Underwear that seems fine for 20 minutes can become annoying after five hours of sittingespecially if the waistband rolls, the leg opening bites, or the fabric traps heat. In 2025, high-rise briefs and hipsters are winning for desk days because they stay stable when you move from sitting to standing, and the waistband spreads pressure across a wider area (translation: less digging). Many women report that a slightly higher rise also prevents the constant micro-adjusting that happens when a mid-rise waistband sits right at the bend of your torso.

2) Travel underwear has its own job description. A “cute” pair can lose its charm quickly on a long flight, a road trip, or a day of walking. The underwear that gets rave feedback for travel tends to be breathable, soft, and forgivingoften cotton-forward or modalwith seams that don’t leave marks. A common 2025 move: pack one no-show seamless pair for leggings days, but rely on breathable everyday pairs for the bulk of the trip. If you’re doing humid destinations, women frequently prefer underwear that feels dry quickly and doesn’t hold sweat.

3) Workout underwear is a “timing” issue as much as a fabric issue. Even the best moisture-wicking pair can feel gross if you stay in it after class. Women who report fewer irritation issues tend to change promptly post-workout, especially after high-sweat sessions. The underwear that earns loyalty in 2025 usually has stable edges that don’t migrate during movement (wedgies are not a sport), and a gusset that stays flat. Another common experience: when people hate thongs, it’s often because the fit is too tight or the fabric doesn’t glide; when they love thongs, it’s usually a well-designed performance thong that stays put without friction.

4) Summer underwear is basically climate control. In hot months, women often shift toward breathable cotton or cotton-gusset styles, and reserve heavy synthetic pairs for short windows (like a specific outfit). Many say the “best underwear” in summer isn’t the cutestit’s the pair that reduces sweating, feels airy, and doesn’t cause inner-thigh rubbing. Seamless no-show styles can still work in summer, but the favorites tend to be the ones that feel light and don’t trap moisture.

5) Period backup is an emotional support strategy. Even if you don’t use period underwear as primary protection, a couple of dependable backup pairs can reduce stressespecially for long meetings, commutes, or overnight. Women often describe the biggest benefit as mental: fewer “did I leak?” body-check moments. The best experiences usually come from choosing the right absorbency level for your use case and following care instructions closely, because performance fabrics can degrade if treated like regular cotton.

6) Bodies change. Underwear should adjust, not punish. Postpartum bodies, peri-menopause, weight changes, and simple aging can change sensitivity and fit preferences. A common 2025 underwear “upgrade” is switching to softer waistbands, higher rises, and fabrics that feel gentler on the skin (cotton and modal are frequent favorites here). Many women report that what used to feel fine (tight lace, narrow elastics) becomes less tolerable over time, and that comfort-first options don’t have to look like “sad underwear.” The market finally caught up: you can get supportive, flattering cuts that still feel breathable and kind.

The big takeaway from these experiences is simple: the best underwear isn’t one magical pair. It’s a small rotation that matches your real life: breathable everyday pairs, a couple of no-show options, workout-specific underwear, and a few specialty pairs (lace, period, or shapewear-lite) for the moments you actually need them.

Conclusion

The best underwear for women in 2025 is less about chasing a single “top-rated” pair and more about building a smart lineup: breathable everyday underwear, no-show seamless options, and workout pairs that handle sweat and movement. If you want the fastest path to comfort, start with breathable cotton (or at least a cotton gusset), choose cuts that match your body’s preferences, and treat underwear like the performance layer it is.

Because honestly? Your underwear should be supportive in the emotional sense too: it should keep you comfortable, confident, and free to think about literally anything else.
