A battle jacket is, essentially, a jacket covered with punk/band patches and worn to concerts...
...buuuut I'm a massive poser and call mine a battle jacket despite it being covered in patches by artists and worn primarily to pride events and conventions!!
Which, if you think about it, is still heading into battle.
I'm gonna try to list all the patches on my jacket here, but I've lost a lot of the artist infor for several of them since they were bought at conventions. Also! I'm not great at sewing these on and the jacket is kinda weirdly made, so some of these are a little lumpy looking! It gives it character. *nods*
If you recognize anything I couldn't remember, let me know!
