I took a chance on these. I love how they fit, soft, stretchy lace, I can’t tell I’m wearing them. I ended up buying more. I would say they are true to size.
I finally found a panty that doesn't ride up. This brief is very comfortable. I first bought a size that was too big, and it that caused it to ride up. When I bought one size smaller, (XS) my correct size, the panty stayed put. Because of the lace trim, the panty line is not really visible under my pants.
These are very comfortable and wash so well. I initially ordered and XS and loved them. Went back and ordered 3 more pair, but I ordered them in a Small. Should have stuck with the XS as S is a little too big. For reference, I’m 5’3” and 112 lbs.
