Rubie's Official DC Harley Quinn Jumpsuit, Ladies Costume Super Villain

How stretchy is this costume? Just a bit concerned the small may not fit me if there isn't a lot of give..

Please could you tell me if you will be getting any size 14s in this Harley Quinn Costume

Lea the hat fill out?

Will you have a l size soon? i am 5'8" and a size 12, according to the size guide l is the correct size for me. is it worth going up a size to xl?
