What women say after a full day.

Way better than expected!

I've tried so many other brands hoping to save money, but I'm glad I gave these a try. So far I've bought two, and I'll be buying a couple more. I have a small waist but bigger hips, and these are perfect to slim me down just enough and smooth out my bumps and edges. From behind, they make a wider butt look so much better. I have a pair of very sheer white pants, and you cannot see these underneath. I bought the nude. I'm 5'10" and about 145 lbs, and I bought the XS/S. No lines show through on the thighs either. I love them.

Taylor

Amazing

Exactly what I was looking for! I'm 5'3", so these come to just above my knee. I have hips and a butt with a little bit of lower belly (waist 29, hips 47), and these smooth everything perfectly. The waistband is the perfect width. No pancake booty, and they even help round out my hips! You will not be disappointed!

Imani

Smooth and snug!

I'm in my early 70s, 5 feet tall and 118 lbs at most. They slip down a little, but no one can tell, and they still fit snug. It won't be a problem for me. They're smooth all over and give your bum a subtle lift. I also like that they're well made and the material breathes.

Works for a 50-year-old butt!

Losing too much weight, gravity and the big 5-0 left me with a negative butt. I'd been searching without much luck for anything that would give me some shape until the squats pay off. This is the only one that actually works, and it rarely shows any lines under my clothes. The compression does the trick. I have both the black and the nude in XS/S, and the top doesn't roll down on me. Try it!

I highly recommend this!

I'm 5'6" and 180 pounds. I thought it would be too tight when I opened it, but it stretches really well. It has slimmed my stomach and lifts my butt, giving me a nice hourglass figure. It's great for work or under leggings. It also makes me stand up straighter. It's much better than any name-brand ones I've tried. I even ordered two more so I can wear one every day while the others air-dry. A few girls at my job have ordered them too, after noticing a difference in my body shape.

R.

A must-have!

I was surprised by how comfortable this shapewear is! It gives firm tummy control without feeling too tight, and it really smooths everything out under dresses and jeans. The butt-lifting design works nicely; it shapes without flattening. The fabric is soft and breathable and doesn't roll down, which is a huge plus. Perfect for everyday wear or special occasions.

Fran G.

A must-buy!

Buy these! I visited Paris last week during a record-breaking heat wave, and they saved my vacation. They were comfortable, light, airy and, most of all, effective! No chafing and no redness after walking almost 10 miles a day for several days in a row. They also didn't roll at the waist or thigh. Absolutely buy these for under dresses!

Jillian S.

Every woman needs these

One of the most underrated things I've ever bought. I got them hoping they'd stop my thighs chafing when I wore long dresses on my Europe trip last summer, and boy, did they work. They were the perfect length to keep my legs from chafing, and so comfortable! I wore them under both flowy and form-fitting dresses, and you couldn't see them under either. I had no problems with them rolling up. I gave my mom a pair too, and she loved them. We'll definitely be getting more before our next trip.

Erin

Smooth and non-restrictive

For the girls who hate tight waistbands but need something under a dress or a nice outfit. I'm 5'5" and currently 155 lbs, eight months postpartum from a C-section (not my first). I struggle with bloating, and my waist is 33 to 35 inches right now. These are so silky and buttery soft. They do the job I hoped: they cover underwear lines, smooth and support gently where needed, and they're not too tight at the waistband. The legs stay in place and don't roll. I love that there's no spillage of fat or loose skin over the top. It's a gentle slope from skin to garment. My very sensitive belly does feel a little extra tightness at the top band compared to the rest, which I'd rather not have, but it's definitely tolerable and lasts through an event or date night much better than regular spandex undergarments. Very breathable, too. I'll be wearing them under a bridesmaid dress this weekend.

Liz

Seamless

I was skeptical about ordering these, because it's been hard to find something that gives shape and is truly seamless, and these are it! I'm 5'7" and 128 lbs, and I got the XS/S. They're seamless under clothes and dresses. Comfortable and supportive.

Becky

Doesn't roll down and isn't tight on the thighs

Update: over a year later, this shaper is still top-notch. After a dozen washes it hasn't lost its shape and is holding together very well. I recently got the black one, and it's the same great quality. It's jet black and seamless under dark clothing. Very comfortable and breathable. It hides imperfections, it's very flattering, and it stays in place! My first impression: lightweight, smooth, and it sucks you in with nice compression. I like it because it doesn't roll down and isn't tight on the thighs.

Ashleigh

Works well, comfortable, stays put

I haven't really worn shapewear before, and I bought this to wear under a very tight dress. It really smooths out my belly and hips, and it's so comfortable and stays in place. As someone pretty new to this, I'm very pleased. It doesn't feel too restrictive, but it definitely makes a difference. I've had no issue with it falling down or riding up, and I usually struggle with that in other clothing.

Mikaela J.

Comfortable enough to forget you're wearing them

These are incredibly comfortable, soft and breathable. I got the XL/XXL; for reference, I'm 5'7" and 165 lbs. The fit is secure without feeling overly tight. Even on days when I'm bloated, the waistband doesn't dig into my stomach or roll down when I sit. The legs stay in place without riding up as I move, which I've struggled with in other shorts. The fabric is lightweight and breathable, which makes them comfortable in the Arizona summer heat. I wear them under skirts, dresses and even some shorts to prevent chafing. They create a smooth layer without adding warmth or bulk. I've washed them multiple times, and they've held their shape and softness very well.

Kari S.

Not bad at all!

These are exactly what I was looking for. I wanted the nude to wear under a dress with a white skirt, and I can see them coming in handy under shorter dresses too. They're soft enough, snug enough and stretchy enough, and not pinchy around the seams, so the fit is nice. For reference, I'm 5'0", about 113 lbs, with a 28-ish inch waist, and I got the XS/S. I'm glad they aren't as stiff as more rigid shapewear. I find those almost more unflattering than nothing, because they're so tight they just push your looseness around. I'm a two-time mama and just turned 38, so a little smoothing is necessary even though I'm small by measurement, and these do the job without feeling uncomfortable.

Desiree M.

Just the right amount of tummy control

I wish I'd bought these sooner! The fit is great, and they're the perfect length under summer skirts. They hold your tummy in just enough without feeling restrictive. Very comfortable, and the top doesn't roll down either. Great material.

Liz W.

All-day comfort

Time, gravity, childbirth and weight changes are not kind to a woman's body. Some of my most comfortable skirts and loose pants leave me miserable after walking 4,000 to 7,000-plus steps a day. Chafing is no joke. These super soft shorts do a beautiful job of protecting against chafing without the squish of many shaping undergarments. I love a good shapewear piece as much as the next gal, but for everyday mom life and work, I don't want to feel like one and a half sausages stuffed in one casing. I can comfortably wear these all day and never feel squeezed in. My slight apron belly is kept off the tops of my thighs, which prevents sweat and chafing there, as well as the dreaded chub rub. I wore these in 90-degree heat with no problems. I'm 5'7" and 218 lbs.
