I strongly advise to never wear a tie and braces that are the same. Solid colored braces that pick up a color elsewhere always work.
If you have never considered a fedora, try one like this beauty from Bruno Capelo. Defintely a memorable touch.
Select accessories that enhance a complete look, not detract from it. Here, its complementary rose gold to weave in with the browns.
Even with a bunch of unique accessories, monochromatic outfits can be developed nicely and look amazingly sharp.
The brown/gold connection develops down below with these Celchuk shadow stripe socks and Whiskers two-tones laces, adding a nice unique touch while keeping with theme.
I always love finding outside inspiration to guide my thematic sartorial developments.
