Best Boyshort Underwear for Women of 2026

Four pairs, a light knit, and a leg that runs longer than a standard boyshort — the wirarpa pack is built for a different job than our top pick, even though the two sit at the same price.

Under a dress or a skirt, these are the ones we rate highest here. The leg is long enough that thighs don't rub, the surface is smooth enough that it doesn't catch on a lining, and the wide waistband keeps everything anchored without rolling down. For a summer spent in dresses, that's the whole job done.

Sizing is the catch: they run small, so go up a size if you're between two. Treated as a layering piece rather than a short you wear on its own, they're the best value in this group for under-dress duty.

Six pairs for less than the Calvin Klein single on this list — the arithmetic is the entire pitch, and it's a good one if you need underwear rather than an occasion.

What arrives is a smooth, stretchy knit that sits close and stays there, with no seams to show under leggings or a pencil skirt. One caution: this listing spans more than one cut, so check that the pack in your cart is the boyshort rather than the bikini or the thong.

We treat them as the working pair in the drawer — fine for a workout, fine for a laundry day, not the pair we reach for under a dress. Sizing is genuinely split, so use the chart rather than your usual number; the stretch means a slightly-off pair still functions, which is more than we can say for a stiff cotton brief.

There is no elastic band around the leg opening. The fabric is turned and finished instead, so the edge sitting closest to the crease where thigh meets cheek is soft rather than gripped.

That one detail is why we rate these the best full-coverage pair in this group. The seat extends past the leg-butt junction, the cotton is dense and soft rather than thin, and they stay put without rolling down through a day of moving around.

The leg is the thing to weigh. It's shorter than a true boxer brief — it covers the crease but stops well above mid-thigh — so treat this as a panty with real coverage rather than a bike short. If you want fabric between your thighs all day, the Molasus cut gives you more of it.

Bamboo viscose is what separates these from every cotton pair here. It feels cooler against the skin, moves moisture instead of holding it, and stays dry through a sweaty afternoon in a way heavy cotton doesn't.

The waistband is wide and flat, the coverage is full, and the breathability is the best in this group — we wore these through a hot, active day and never got the clammy patch a nylon pair produces.

The trade-offs are price and fit. This is the most expensive pack here, and the sizing runs small, so check the chart and lean up rather than down.

We keep these for heat: outdoor work, a summer commute, a day when the forecast is going to be miserable. The fabric is the reason, and it's a reason we're happy to pay for.

Start here if your weekday uniform is leggings. The seamless knit sits flat under anything tight, the waistband doesn't dig, and we never once had to adjust them through a day of errands.

The nylon blend is soft and cool to the touch, with a stretch that conforms rather than squeezes. Sizing is the weak point — these run large and the leg is short, so check the chart and consider the smaller of two sizes if you're between them.

Five pairs at a budget price, they launder well and dry fast, which makes them the pack that goes in a suitcase. In a drawer full of cotton, they're the ones for tight clothes and travel.

There's no pack and no spare: the Calvin Klein boyshort is one pair, priced like a treat. Whether that makes sense depends entirely on what you want from it.

The cotton is thin, smooth, and the softest in this group — that's the whole case, and it's a real one. The cut is a true boyshort with a clean, low leg line that vanishes under a slip. Fit is inconsistent, so try your usual size and be ready to move one either way.

We keep ours for the days that deserve it: an evening under a dress, a long day when you want the softest thing you own against your skin. It isn't the workhorse of a drawer, and it isn't meant to be.

The rise is the thing to pin down before you buy. These sit high on the hip, but the name oversells it: on a short torso they land lower than a true high-waist cut, and on a longer one they behave exactly as advertised.

The detail we like most is the wide band at the top of the thigh, which supports without pinching and keeps the leg from riding up during exercise. Coverage is full without looking like shapewear, and the cotton is heavyweight and breathable.

A raised logo sits on the front waistband. It rules the pair out under thin or sheer fabrics, and it's the kind of thing that peels after a few washes — worth knowing before you plan outfits around them.

Taken together, they're a solid cotton four-pack that finishes just behind our top three: comfortable, flattering, and slightly undone by finishing details. If a wide thigh band and a full seat in cotton are what you're after, they're worth a try.
