What is the most comfortable women's underwear?

The most comfortable women's underwear is made from soft micro-modal with a little spandex, in a cut that suits your body and your day. For most people that cut is the boyshort. Culprit LadyBoxers have a mid-high rise and a 5 3/4" inseam, so they cover and stay put without squeezing.

Comfort comes down to three things: fabric, rise and leg. Fabric first. Culprit pairs are 95% sustainably made micro-modal and 5% spandex. Micro-modal is a plant-based fabric made from beech wood pulp, and it is a type of rayon. According to Wikipedia's entry on modal, it is smooth, resists shrinkage and is more absorbent than cotton by volume. The spandex adds stretch so the pair moves with you.

Rise matters just as much. LadyBoxers have a 10 1/4" rise, which sits above the hip and higher on the waist, and that is the reason they stay in place when you sit, bend and walk. Browse all LadyBoxers.

More than 14,000 customers have left reviews on Culprit pairs. Most single pairs cost between $13 and $35. They come in funny limited-edition prints, so the inside of your life can be as loud as you want while the outside stays professional.

Boyshorts (LadyBoxers) vs briefs vs thongs: which is most comfortable?

Boyshorts are the most comfortable for most people because they offer full coverage and a leg band that stays put. Thongs suit tight clothing and visible-line worries, and briefs sit in between. Comfort is personal, so pick the cut that matches your clothes and your day.

Cut	Coverage	Best for	Culprit option
Boyshorts	Full, with a short leg	All-day wear, sleep, thigh comfort	LadyBoxers (mid-high rise, 5 3/4" inseam)
Longer boyshorts	Full, with extra length	Dresses, skirts, thigh rub	Long LadyBoxers
Booty shorts	Cheeky, low rise	Low-rise pants, a playful fit	Booty Shorts (low rise, 8" rise, 3" inseam)
Thongs	Minimal	Tight clothing, fewer lines	Thongs (mid-rise, 9 1/4" rise) and Hi-Cut Thong

If you are new to boyshorts, start with LadyBoxers. They are the pair we would hand to a friend who says she hates underwear. If you like a lower rise and a cheekier fit, Booty Shorts are the cut to try, but size up because they run small.

Not sure which size? Use the size guide. Sizes run by waist: S is 26 to 28 inches, M is 29 to 31, L is 32 to 34, XL is 35 to 37, XXL is 37 to 41 and 3XL is 42 to 46.

What is the best anti-chafing underwear for thigh chafing?

For thigh chafing, choose a longer inseam in a smooth, stretchy fabric, and Long LadyBoxers are Culprit's answer. They have a longer inseam than LadyBoxers and extra coverage, so skin has less chance to rub on skin. Pair them with a skirt or dress for a quiet fix.

Thigh chafing is about friction and moisture. Three things help. First, a longer leg covers the spot where thighs meet. Second, a smooth fabric gives skin something that glides instead of grabs. Third, the right size matters: a pair that is too small can dig in at the leg, and a pair that is too big can bunch and rub.

Long LadyBoxers have a longer inseam for more thigh coverage. Browse the Long LadyBoxers collection. For regular days, standard LadyBoxers with their 5 3/4" inseam may be enough. Just keep in mind that no underwear is a medical product, so if chafing is severe or constant, talk to a doctor.

What is the most comfortable thong?

The most comfortable thong is a stretchy, smooth pair with a mid-rise waistband that stays flat. Culprit thongs are mid-rise with a 9 1/4" rise and are made from the same micro-modal and spandex blend. A Hi-Cut Thong is also available for a higher leg line.

Thong comfort depends on fabric and rise. A rough or stiff fabric will irritate, and a rise that is too low can slip or dig. The micro-modal blend is smooth and stretchy, so it gives with each step, and the mid-rise waistband sits where most waistlines sit. If you love a thong under fitted clothes, this is a good place to start.

Sizing tip: choose your usual size by waist from the size guide. Shop thongs. And if thongs are not your thing, no judgment. Plenty of people wear LadyBoxers and are very happy about it.

What is the most comfortable underwear for sleeping?

The most comfortable sleep underwear is soft, stretchy and free of anything that digs in, and LadyBoxers are a strong pick. A mid-high rise stays put while you turn, and the short leg won't ride up the way some cuts do. Choose Long LadyBoxers if you want extra coverage.

You spend a third of your life asleep, so it is worth caring about what you wear. Smooth micro-modal reduces friction against sheets and skin. The 5% spandex lets the pair stretch as you roll over, so it does not twist or bunch. If you like to sleep in a bra, the wireless options below keep out the underwire.

What is the most comfortable underwear for hot weather?

For hot weather, choose a breathable fabric and a leg that prevents thigh rub. Micro-modal is breathable and absorbs more than cotton by volume, so it is a good everyday choice in summer. Long LadyBoxers help when thighs rub, and thongs or Booty Shorts give the least fabric.

Summer comfort is friction plus moisture. A smooth fabric reduces friction, and a breathable one helps with the moisture. If you spend your summer in dresses and skirts, Long LadyBoxers make a great base layer. If you prefer minimal fabric, Booty Shorts have a 3" inseam and a low rise, but size up. For extreme sweat from hard training, performance polyester can wick faster, and we cover that below.

What is the most comfortable wireless bra?

The most comfortable wireless bra has no underwire, a smooth fabric and a design you can forget about, and the Culprit ComfyBra and Scoop Bra both fit that description. The ComfyBra has a scoop front and racer back. The Scoop Bra has an inner mesh lining and a low U-back.

Here is how the two compare:

Bra	Support style	Design
ComfyBra	Wireless	Scoop front, racer back
Scoop Bra	No underwire, inner mesh lining	Low U-back

Bras cost about $33 to $35. Pick the ComfyBra if you like a racer back, and the Scoop Bra if you want the inner mesh lining and a low back. Both skip the underwire, which is the part many people are happy to leave behind.

One honest note: wireless bras offer a different kind of support than underwire. If you need maximum structure or lift, or you are doing high-impact sports, a structured or sports bra may serve you better. Culprit bras are for comfort-first, everyday wear.

What is the softest women's underwear?

The softest women's underwear is micro-modal, which feels smooth and silky against skin. Modal is a plant-based rayon made from beech pulp, and micro-modal is a finer version. Many people find it softer than basic cotton, and it tends to keep its feel with gentle care.

Fiber and knit decide softness. Cotton can be wonderful, but basic cotton may feel rougher and can shrink or stiffen. Bamboo viscose is also a rayon, so it can feel close to micro-modal. Polyester tends to feel slick instead of soft. For the full face-off, read micro-modal vs cotton underwear.

Fabric	Feel	Breathability	Best for	Watch out for
Micro-modal (Culprit)	Very smooth	Breathable	All-day wear, sleep	Not built for heavy athletic sweat
Cotton	Varies by quality	Generally breathable	Basic pairs	Tends to shrink more and dry slower
Polyester	Tends to feel slick	Varies	Hard training	Tends to feel synthetic
Bamboo (viscose)	Generally soft	Generally breathable	Everyday wear	Stretch depends on blend

When is Culprit not your pick?

Culprit is not your pick for heavy daily training, or when you need a bra with maximum structure. Culprit is a lifestyle brand. Performance polyester wicks sweat faster, and structured bras offer more lift.

For everything else, work, travel, sleep, dates and weekends, we think you will be very happy. Try your first pair risk-free: your first pair on a first order has a 100-day money-back guarantee. Worn or washed pairs cannot be returned, so try them on over something first. Free U.S. shipping applies on orders over $99.

How do you care for comfortable underwear?

Machine wash cold on delicate, then tumble dry low or air dry. Gentle care protects the stretch and the soft feel. Skip high heat. When a pair finally gives up, check how often to replace underwear.
