New Shoes... what Suit goes with them?

You can only wear those with green suits.

Those look lovely. Are they Lobb?

 

Anyway, you can certainly wear those with navy suits, but med to light gray would also work, as would shades of brown. Personally, I think brown shoes with a charcoal suit is very doable as well, but some people would disagree with me on that one.
 

I love 'em too, but I'm not sure that's a great choice for your first, not too mention one-and-only, brown shoe. They are fantastic, but the "museum" brown color (that's the sort of "mottled" or "burled" brown look) is pretty distinctive. If you were hesitant to jump into brown, well, you picked a flashier shade than most brown to land on; the good news is you picked an excellent maker and model, so let's roll with it...

If they landed in my collection, I would have zero problem wearing them with navy (medium or dark), grays (from medium to charcoal, maybe even lighter than medium too) and brown/tans (depending on the color shade/hue).

If I may suggest, look to add another brown shoe just so you can get some rotation in that area. Regardless, don't let these hold you back - get them into rotation and enjoy!

without a flash on those shoes they probably look pretty conservative. nothing at all to worry about.
