Rags to Raches romper

Rags romper from 2014. Original owner, raw neck, hard to find. There is no size listed but looks the same size as our other 12/18 month rags. The graphic is in great condition with basically no cracking. The romper has some piling. There are also too spots on the back of the romper (see pictures) I am not sure what it is but doesn’t affect wear.
