This bralette is a sports bra style and I LOVE IT! It isn't often that I can wear one which really hinders me from wearing styles that I want, including off shoulder ones! I am a 34DD and the S/M did great! I suggest ordering the size that includes your typical shirt size! Wear this with a regular bra under it to add a strappy detail to your V neck shirts, or wear it by itself with an oversized off shoulder shirt and biker shorts!
