Unworn old stock, men's collarless shirt from the Edwardian - 1920's.  The shirt is a white cotton dimity with narrow black stripes.  Tri-State label. If you love old...like new condition, here's a shirt for you.

Still tied and pinned in the original packaging, so without undoing, I haven't inspected the shirt completely.  This is what I can tell you.  Buttons down the front with pearl buttons.  Collar stud at the neck line  It is long sleeve with stiff cuffs for cuff links. 

Collar size is 15-1/2.  Other markings I found were 33-35  About 18" across the shoulders.  A crispy fabric which would need to be laundered to remove oxidation.  

Found with this shirt, an Arrow men's shirt from the same time period.  Please see in other listing.
