I'm probably the wrong person to ask, but id say odd jackets.
Like with ties, there may be better options, but I dont think its inherently wrong.
Maybe casual suits too, but this may be more of a stretch.
I didn't really like them to be honest. I had a paid of black shell ae ptbs and ended up selling them. I also don't like black shoes that much unless I'm wearing black boots with jeans. Still looking for black Chelseas, but I wear black suede chukkas often. Casually though!
