Happily surprised!

Ashley FritzkeOctober 11, 2024

I was thinking it wasn’t going to do much of a difference because of the material but I was pleasantly surprised! I got my normal size of XL and it wasn’t tight at all and felt very comfortable. It held in my remaining c-section belly so nicely and made a very big difference. It also didn’t cut in weird on the butt or the hips. I will definitely be ordering some in other colors. Read more

Comfort

L ONovember 16, 2023

It is very comfortable for a thong. I had to order a larger size. I tried these on with a pair of jeans. They fit well and didn't roll down. I hate having to adjust my panties while wearing a dress. I suspect they were not designed to have a lot of hold. Still I didn't see any panty lines. Read more

Worth the money

CustomerMarch 1, 2019

I’m wearing a very firm-fitting dress for my wedding, so I wanted to get something that would just smooth me out a bit. For reference, I’m 5’2” with a 24.5” waist and 36” hips. The XS fit me perfectly, I really don’t have complaints. It is as comfortable as you’d expect for shapewear and gives a good amount of compression. It could be a little tighter around the waist, but that could also cause a bit of a bulge on some people, so I think it’s constructed to prevent that. I’m very happy with the quality and effectiveness. Read more

Sizing isn’t consistent

Lanie BJuly 29, 2023

How to charge king the size chart in measuring myself I bought a large, I tried it on and it was a little bit too big on me even though the sizing chart said that shouldn’t be the size of fit me so I ordered a medium because I did like the quality and feel of the fabric and the medium to be perfect so I ordered for the third time and medium so I could have a back up pair and a medium I ordered originally fits perfect by the medium I just ordered and received is way too small. This is all in a span of like 30 days and I’ve actually lost weight says really on the medium doesn’t fit. I held them up next to each other and they definitely are not the same. I really like the material. I just wish the sizing was consistent. I’m unable to wear my most recent purchase from them . I just ordered and made informed version of this and if it’s great it is just as comfortable for less. Read more

Must buy ladies!!

Mady DavisJuly 20, 2025

SO SOFT! These are so soft and they actually do a decent job of shaping. I am so glad I bought these especially for more everyday items versus full coverage. Read more

Not for my mom bod

JessiFebruary 27, 2023

My natural waist measurement is 33" and my hips are 45". I normally wear a size 12 in pants and I meant to get the XL but I accidentally got L. I was able to get them on but they were snug. It didnt feel right to return panties lol so I kept them. As I wore them throughout the next day they stretched out A LOT so they were more than roomy enough, but they kept rolling down or riding up too high to hold in what I need it to hold in (I have a lower belly "mom pouch"). I was expecting them to be of better quality than what I could buy from WalMart but it just isnt... the construction of the panty didn't look neat or sturdy or worth 25 dollars a pair at all. Maybe 12 dollars. Overall, they create more lumps and bumps than they hold in *for me*. They may work well for women that are shaped differently. Read more

Buy the right size

sierra kerrApril 5, 2022

I'm in-between a med and lg and wore a medium under a dress to a wedding. It was snug and had a little roll over, but looked better than nothing. I bought the lg and love them. Perfect coverage with no rolls. Holdsu stomach in and no underwear lines. Read more

Perfectly Invisible

Robert KrolakAugust 5, 2020

I was looking for something to wear with yoga pants where you couldn't see the lines. I was surprised by how comfortable they are, I normally don't like thong underwear. I love the wide waistband on them which smooths things out. I didn't really buy them for the compression and I can see why some people would think they don't do enough. But they do say they are light compression, or something like that. They work perfect for my needs and I bought a second pair as well as tried another style by Spanx. Read more
