I bought the medium, 5'5" 150 lbs, and it fits perfectly. The button and crossover piece are lovely and add to the vibe. It is very comfortable and classy LOVE IT!
This piece is long and elegant but casual and easy to wear. The pearls are delicate but not so symmetrical as to look molded, and the tiny brass beads give it a bit of weight and glimmer. I love it.
