Pottery Barn Kids T-Rex Costume- Lights Up! NWOT Purchased this from someone that incorrectly estimated the size as being 3T. The sizing tag is cut out so I am unable to determine exact sizing but this fits my 8 year old son that is 48” tall & weighs 56lbs. He wears a size 7 or a size youth small. I’m guessing the costume may be closer to a size 7. The costume is NWOT, never worn. Retails on PotteryBarnKids website for $99 and shipping is an additional $19.
