SIZE UP! The measurements listed are not entirely accurate. I ordered a 3T for my 2 year old niece after measuring her. When it arrived, it wouldn’t zip because it was too small. I re-ordered a 4T and while it fits, it’s still very snug. Also, be aware that if you exchange an item, you’ll be paying for shipping 3 times (for the initial item, for the return, and for the replacement item)
