This suit highlights all the right areas and hides all the others. I'm 5'7", 118 lbs., and wear a C cup. I tried the medium first because the girls usually need a little extra room, but the medium was too big in the trunk and bottoms and not at all flattering. I returned it and got the small.It avoids a lot of pitfalls I see in most tankinis, which I generally find unflattering and shapeless.The tankini shows off my best features on top. The top is long enough and doesn't ride up. It has a tapered fit through the waist but is not a tummy control (which I didn't want). The bottoms are a flat skirt with a built-in panty. The skirt has a slit on the front with ties so you can add a little more flair. The built-in panty provides full coverage, so no worries if you bend over or the wind gets your skirt! I like that the skirt is flat without ruffles or tons of extra fabric. It's just long enough in back for me to feel confident walking around the pool or the beach.Bonus: It's easy to swim in! It didn't ride up or move or drag the water.The only thing I don't like about this suit is that I didn't have it sooner. It makes me feel like a million bucks. I bought two more in different colors and moved all my old suits to the donate box!
