I am trying to order some shirts on ShopDisney and am struggling. My daughter and her friend have just outgrown the Disney brand XL. Technically it fits but the shirts are more snug than they'd like. Would you go up to an adult XS or a small? We live quite far from the nearest Disney store so it's tough to go look. Examples of other sizes they wear: L in Cat and Jack and XXL in Gap. I swear kids clothing sizes are made to make parents go crazy.
