I filed this under our ‘retro‘ tag only because we didn’t have a ‘super retro’ available. I have no clue when this is from, but obviously it’s from way back.
I’m not too knowledgeable on old style clothing, but are these boxers wearing ‘petticoats’?
According to wikipedia women’s boxing first appeared in the Olympic Games at a demonstration bout in 1904. For most of the 20th century it was banned in most nations.
