Something like the picture here. I want to wear that, it'd rule. I cannot for the life of me find a sports coat that isn't navy / black / blue / gray / dark green at best.
I've been to second hand stores, I've scoured the internet. My options are 500€ designer shit, which, no, not for a trial run and probably not ever, or polyester stuff from china that is gonna ensure I look like a melted candle wearing it and is probably made to fit for like an asians person frame not my golem ass
Where, I ask, where!
Don't despair. Most places seem to have active men's fashion subcultures and in my experience, aside from some jerks, folks are happy to help new enthusiasts find their way around the local terrain.
I'd know where to find one but it'll be a trip
