I’m 5’11 155lbs 36DD. if you know you know! most brands I’m one step away from being two sizes too big or too small! ordered in a medium and was skeptical but it fit perfect! not only perfect but roomy, comfy & still shape wear! I could easily fit a small if I want to squeeze everything in more! but the medium will do as it is super true to size. but for those of you who can should size down!
