Im 53 175 pounds, regular size 8 pants/medium shirts, 38C. I ordered the medium and it fits great! It was. A little shorter in the back than I expected, but I also have a large bum so that shortens it in the back a tiny bit. However, its not too short on me and doesnt reveal anything, just shorter than expected! I would be weary on the shortness for taller individuals as I am a short stack. Anyway, great great buy!!! Its such a complementary style on my body type so I ADORE. I also bought this style in the long version for a not elegant look because its so cute. Dont ask, just buy!!! Best purchase Ive made.
