I have a few items of clothing that I'll be auctioning here but it won't be until after my current listings are over. Since, I'm paying the shipping; I can only afford to put a few up at a time. If you have anymore questions, please feel free to ask.
My guess is, 4T. At least that's what size my daughter was wearing when she was able to fit into this shirt. All it has is a " S " on the tag; which there is a photo of that above.
