25 guys spending their weekend on the fantasy football "draft" or putting on their little sports costumes to go to the bar (and yes, I call sports jerseys 'costumes')

not sure how you can call it a costume. It is not like they are wearing the football pants, helmet, and shoulder pads. They are just where a football jersey and jeans(or some other normal kind of pants) .

If I put on my Darth Vader cape and mask, but wear jeans, people say I'm in a costume.

If someone puts on the uniform of a sport they don't play, or a team they're not on, with someone else's name on the back, looks like a costume to me.
