I am 5' 1". I weigh 160 pounds. My bust is 42" (36 DD). My waist is 37". My hips are 43". I am in between a size medium and large (8-10). About 95% of the time I order my items from ByEgreis in the size medium. Unless Egi states to size up due to bust size or lack of stretch. This info has never steered me wrong in choosing my size accordingly. That being said, I ordered this GORGEOUS blazer, in a size large. Its a TINY bit tight in the upper arm area. But that's because I gained 5 pounds. I need to get my ass to the gym! LOL The pictures of this blazer do it NO justice, compared to when you see it in person! It's stunning! I also like the versatility of wearing the blazer as a dress, or a jacket. Not surprised it sold out. Make sure you sign up for notifications. I cant tell you how many times I've lucked out with inventory they find after items are sold out.
