    • Happily surprised!
Size: X-Large Color: Very Black
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. ... show more

    • Comfort
Size: Large Color: Very Black
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.

    • Worth the money
Size: Small Color: Soft Nude
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. ... show more

    • Sizing isn’t consistent
Size: Medium Color: Very Black
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. ... show more

    • Must buy ladies!!
Size: Large Color: Cafe Au Lait
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.

    • Not for my mom bod
Size: Large Color: Soft Nude
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. ... show more

    • Buy the right size
Size: Large Color: Very Black
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.

    • Perfectly Invisible
Size: Small Color: Soft Nude
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. ... show more
