Bought a pair of black lace Natori bikinis years ago and they were very good quality and fit. So thought I would give these a try. I am tired of super high rise panties and boy shorts that no longer feel comfortable around the leg/groin area. Wasn't too confident the "one-size" would fit; so surprised these do fit and don't dig in. I have a flat butt, so I think that helps with rear coverage and they don't ride up . I am 147 lbs 37" hip 33" waist. Once I loose the 8 pounds I am striving for, the fabric won't be stretched to the limit. The Iris color is very pretty.
