This is a Halloween pumpkin romper and hat set. There is no size indication, but it was loose-fitting when worn around 6 months old. It's the type that adjusts with strings on the back, so it seems like it could be worn for photoshoots up to around 1 year old. It was only used for photoshoots and is in good condition, but please understand that it is a used item worn by a child before purchasing.
