This shirt is preowned with normal wear and washing.  Flaws are two pinholes at the left rear hip (pictured) and no size tag.  However it measures very mush like a modern day adult XS or a youth large.  

Please see all pictures and approximate measurements for the best description and ask any questions that you may have.  Please see my other listings by clicking "see other items" under my user name! Thank you.
