Rubie'sWomen's The Hunger Games Katniss Costume "the Games" Catching Fire Adult Sized Costumes (pack of 1)

My daughter is a size 10-12 girls, what should we get for her, the small or the medium? She is very thin but tall

If I wear a dress size 2 and I am 5'2, 118 lbs. should I buy an xsmall or small in this costume?

I want to wear this as a figure skating costume. Will it move well for athletics, or is it flimsy & tight?

I’m 5’3 and weigh 100lbs, i’m incredibly skinny and would like this to fit me snuggly. should i go for youth sizes or go with xsmall?
