Hello dancers!! I’m a dance student in Shanghai Dance School, but right now I am in LA visiting my friend for 3 months. I am afraid time is too long here without my dance practice, so I am planning to participate in some ballet classes while here in LA. My friend helps me to order leotard on the internet, but I do not understand sizing measurement of leotard in US. In China, we use centimeter number for size. On the American website I only can choose from size choices XS, S, M, L, XL. My size is 160 cm and my weight is 46 kg. Can someone help me with how leotard sizes work? Thank you!!
