Comfy
Ah so good. Does not roll. Great comfy fabric. Does not have an intense hold but enough to smooth things out.

Must buy ladies!!
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.

SIZE DOWN
If you really want these to do the trick and hold in the lower pooch, size down 1 size from your normal. I’m a size 12, usually a large and went with a medium.

Rolls down
I bought these to wear under my wedding dress. I brought them to the dress fitting and I’m so glad I tried them on BEFORE my wedding day! They are an awkward fit (for me) and rolled down during the fitting. The search for wedding day undies continues…

Runs small
These run a little small. I like the idea of the waistband but it kinda digs into the middle of your butt cheek creating a weird line that would show thru your clothes if you’re wearing anything fitted or thin material like a dress or skirt. Does hold your belly in. Got both size small and medium. I typically wear a small in clothes and preferred the medium in this so it didn’t cut into me making unflattering bulges

New favorite
I’ve been wearing thongs for a long time, but sometimes when you’re on an airplane or sitting for a long time that’s not the best option. I have started to wear these because they don’t move and they don’t ride up there comfortable and they don’t roll down I’m a size 12 to 14 in large is what you should buy.

No support. Or control for any excess skin. I weigh 151 and 5' 4' & no coverage
No enough fabric regardless of the size

Perfect fit
I’m plus sized and never wear thongs because my cheeks would devour a thin strip of material. I had purchased some pants that I loved but they really showed my panty line. I bought these in hopes they would provide support in the front and these most definitely do. I love the full coverage on the front. And they are actually pretty comfortable for someone that has never worn a thong before.
