Very elegant IST, very elegant.
Yeah, I can see that. It would be easy to wear it as separates, with beiges/white/etc. As a suit, it's tough... open-collar white shirt is an unimaginative option, I guess... maybe ecru shirt and pale/mid-brown tie? Tough, but what a fun suit to experiment with.
Today's chocolate-brown suit on th other hand, that one I'd move onto pastures new. The pattern is just a bit too weird.
Talking of tough-to-coordinate suits...
