I'm 5'2" 165lbs, bottom heavy, small chest. I wear size Large mostly but can fit mediums depending on the material. I got a size large. Glad that I did. This outfit fit well and was form fitting. Def snatched in but comfortable. Drawbacks - didn't know the material was RIBBED, not a smooth black material. I planned on wearing this outfit with a leather RB hat and leather mid calf boots (like the Givenchy shark boot). The textures didn't go together so I couldn't wear the outfit as planned. The outfit's zipper was hard to zip up and down. I had to have my friend help me with the zipper every time. Overall, nice outfit but some drawbacks.
