Got the xs and its perfect!!! I am 163cm or between 53 and 54, 49.5 kg or approx 110 lb, usually wear size xs, 0-2. Waist measures about 61 cm to 65 cm depending where I measure... there is some elasticity so if you want it to be tight don't order up. Material is thick and high quality. Very cute! Pink is a nice bubblegum color.
