Actually, I hope it is standard Resistance wear. I'm tired of the "Poe gave Finn his jacket/name" stuff that led to so much of the slave AU and Finn "belongs to Poe" stuff in the fandom. I'm sorry I mean I know you're being fun and funny with this but I'm serious, Finn needs to get some items of his own. I'm not even really happy he's still wearing that jacket because people still insist on calling it Poe's jacket.
That’s fair and you’re probably right about the shirt being standard Resistance fare. I do like the jacket and I think it’s more strongly associated with Finn than it is with Poe by now (or should be, at least - fandom will be fandom). The Celebration art looks a bit different though, with a more structured high collar that seems like it’s part of the jacket, so Finn probably will get a cool new outfit. Hopefully something fancy and debonair for the casino scenes so we can all swoon. ♥
