I’ll start by saying I am a very curvy girl with a noteworthy large bum. In my 35 years, I have never found anything with adequate rump coverage for me, as the rare items that do cover me quickly turn into a wedgie. I’ve given up on trying to cover my booty and am embracing letting my cheeks be seen, but I still want to look appropriate for family vacations, public pools, etc. These bottoms fit the bill! They sit high enough in the back to not give a plumber’s crack, and are wide enough to cover everything important, while the higher waistband gives me easier movement and a very sexy silhouette. I went by the size chart and ordered a medium, and I do feel like it runs a little snug, but not to the point of being unwearable. It digs in slightly at the hips, but I bet it will fit nicely when wet, as things that fit well dry tend to slip around once you get in the water, in my experience. Docking one star only because the elastic bands on this style dig in a *little* more than the similar plain bikini style I got in another print (the cut is otherwise the same). I am 5’4”, 150 lbs, and have a 28” waist, 38” high hip, and 43” fullest hip around my butt/thighs. I typically wear a size 8/medium in most bottoms.
