Im 15 and me and my 13 year old sister share clothes. She wears a lot of boy clothes and skater clothes that i like. Even though im older, she a little bit bigger than me so they fit good. i can wear her jeans with a belt. My pants her too tight for her, but she wears my hoodies. Together we got like 15 hoodies. And she has like 6 pairs of shoes that dont fit her anymore but fit me. she wears a 8 in mens and i wear a 7.
