I'm familiar with the dress when it was sized as XS, S, M, L, but if I wear a S, what size will that translate to? 3?
Depends on what brand your comparing a small to. If youre talking about a women's small, I would say 5. A Juniors small (which is what this is) would be a 3. I buy medium & wear a 7.
