The dress runs big.

I am 5’1 and 140 lbs. I got a small. It fit beautifully! I had to adjust the straps to accommodate my full B/C cup. There’s not much stretch to the fabric to give a snug fit to the breast and hip/butt area but if you get the right size you’ll be fine. The zipper may give issues sometime in the future. It’s not very sturdy I can’t wait to wear it out in warmer weather. My boyfriend’s eyes got big when I modeled the dress for it.
