Perfect Tommy (Buckaroo Banzai) - What is that jacket???

[RhinestoneBones]

Any Buckaroo Banzai/80's fashion fans out there that can help me with IDing the white jacket Perfect Tommy wears? I'm throwing together a costume for DragonCon last minute and this is starting to haunt me. Google lense didn't turn anything that's even in the same ballpark. I have something coming that's basically just an oversized white blazer that will do well enough, but I'm so curious about this piece. It's a hellish cross between a blazer and a windbreaker and I'm coming up with nothing on ebay/poshmark.

Hope there's some other fans out there still waiting for Against the World Crime League that can help me out
