Women's clothing never has been effectively standardized--at first because it was assumed that women that wanted a good fit weren't buying off the rack, then because women that cared would re-tailor/have things retailored or would move up the price point.

I have short arms and small hands. There are women's jeans I can just fit my hands in. That's too small. I sometimes have problems with sleeves being too short (which might be 3/4 sleeves that are 'almost' full length on me)

Steve lived years condemned to swimming in his clothes, because he was wearing things meant for larger men. He got used to moving about in his uniform (and someone was sewing and not just because of armor.)

Bruce probably was held responsible for keeping his bruises hidden. If your fingers are the only thing poking out of the sleeves...
