I'm 5'7" and 125 lbs. I ordered the medium and it was huge. I definitely need a small. Otherwise, it looks well-made with nice details.. Great, sharp looking suit. Just make sure to order smaller than you think.
They were out of smalls so I ended up getting the Roxy Rizzo black one-piece suit in a small. It's comfy and it looks hot. Keeps me cozy on the slopes when paired with a base layer of Hot Chilis.
