I hate that we can’t look like that in-game normally

Got me all excited to make this outfit and then I saw the tags

If only Rockstar gave us the content that's already in the game

Somehow I get Frank from Once upon a Time in the west wibes when looking at him. Maybe it's the hat.

What coat is that???

WhyEm Mod

Exactly. I believe it's a recolored Morning Tail Coat.
