Runs small
I bought size S but these are rather an XS. But even for an XS the leg openings are super small. Unexpected thick material. Not great for working out.

Perfect Panties
For me, these are the perfect panties. They have enough stretch for a full booty and do not roll or hike up while you are wearing them. I am long waisted so they sit a little lower on my body than the photo, but this also is perfect for me.

Very good and comfortable!
Very comfortable. Doesn’t ride up at all. Waist stays in place and comfortable. (Doesn’t roll)! I ended out buying more.

Well, Aren't These a Treat?
As a chef, I'm a white granny pants kind of gal. But I have been enjoying my new Wacoal B-Smooth Seamless Brief. It is comfortable and fits well, although I had to buy a size up to make sure they didn't shrink on me.
