Happily surprised!
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.

Comfort
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.

Smooth and comfortable
Lived there! I know several reviews say the has to return for a larger size but I disagree. I am 5’5 122 and I ordered a small. They fit perfect and had amazing coverage. There were no panty lines and the offered a pleasant amount of flatness to my abdominal area. Great value for the money.

Not for my mom bod
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.

Sizing isn’t consistent
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.

Buy the right size
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.

Recommend!
Although the order took awhile to be delivered, it was worth the wait. I am very pleased with these Spanx. I wear a 12/14 and ordered a size large. I was concerned that they would be too small but they fit perfect! I also got them on sale. I plan to order more if I can find another sale.

Queda perfecto. Además el tejido no se parece a ningún otro que haya probado. No molesta, no se marca, ni resulta incómodo.

Comfortable, lightweight, smoothing
Lets start with what I was looking for, a lightweight high leg pair of undies to smooth my tummy under a skirt for an evening out, in the middle of a hot summer, where I would be eating. Did they deliver? 100% yes. Sizing, I followed the size chart and chose XL (size 20) and although when I unpacked them they looked a little small they fit perfectly and were very comfortable. Zero roll down, they stayed in place and were easy to replace when visiting the bathroom. The thong was comfortable and I found the overall quality to be good. Now, lets get honest for a min Ladies. No piece of elasticated fabric is going to turn a size 20 into a size 12! However, if you are looking for something Lightweight, fuss free, to give you that little bit of extra confidence and disguise those peskie tummy rolls I would recommend these. They performed the function I was expecting and the colour (Cafe Au Lait) worked well with no shine through under a white skirt. I paid £14.75 for these on offer and thought that was a fair price.
