5'5" 120 lbs, got a medium fits me so so good. I really like the full length coverage of this jumpsuit and the crisscross lace detailing makes for a natural fit. The polyester spandex material is fairly stretchy, lightweight and breathable. This jumpsuit is body sculpting or form fitting, the fabric rest on my skin nicely, it doesn't bunch. Was somewhat skeptical or apprehensive about placing an order, but i have no regrets purchasing this jumpsuit.

Fits perfect
