Got this is May for a July birthday, so I can't return it. I read that it ran small, so I figured 2X might be a little big, but it's a jacket, so irk work. Nope.This might be a 2X in children's sizes. I'd say that this might be a junior medium. It is cute and seems well made, though. But it is TINY! Hopefully somebody ay Goodwill loves it.I purchased an XL for an adult who normally wears a medium. It was actually a size 10-12 for a child - very small. I just gifted it to a child.This product many months to arrive here and upon getting it and trying it on it would fit a six year old and had very long sleeves. Unhappy customer
