I am 5' 3" and 140 lbs. with bust 38", hips 41", waist 32" and torso 63". I ordered a size 12. I haven't worn a swimsuit for 6 years because of my insecurities but have an upcoming trip to Hawaii and needed something I felt good in. This suit is great for hiding my trouble areas (hips, tummy, and butt). I was worried that the chest area wouldn't fit since I have a B cup but large rib cage. I was pleasantly surprised when it not only fit but the halter straps actually help hide my armpit fat!
