Used Single Stitch. The shirt is in good used condition with the normal fading these really old shirts tend to have. The pit to pit seems on par with a small for adults, but the length runs short. See measurement photos. 

Used clothing varies with sizing so I include measurements for people to ensure proper fit.   
Multi-Quantity has cheaper shipping when order is combined.
Pre-Owned Items have all been washed. 
Any questions, feel free to ask.
