Size medium, 2 barbells secure in center. Great vintage condition, however please know that IT IS VINTAGE and not new. There are a few places where the seams could be reinforced under collar (see pictures). There is some running in the liner fabric but this is under the collar and should not be visible when wearing (see pictures).

23.5 inches armpit to armpit and 46 inches from collar to bottom.

I bought this ages ago and have not seen another for sale since.
