Just bought this costume from the Propstore:
The costume on the show seemed to have an undershirt with longer yellow sleeves.
I have two questions:
Any idea who number 11 was in the old TV show from 1979? I have searched hi and low online, and I only found one number 111 from the first movie from 1976: Amanda.
Do "regular" baseball shirts have an undershirt or are they one piece made to look like two shirts?
