It's my understanding that generally people recommend flat black silk laces. I've looked around and can't find a pair less than ~$40 or so and just can't justify spending that much on laces unfortunately.
As I've probably made clear on several threads, I was in the market for shoes for my tuxedo, and ended up buying a very gently used pair of Brooks Brothers patent leather bals for $140:
The problem is, I'm not a huge fan of the round rope-like laces. I have to say I'm rather fond of these laces on the Suit Supply brand patent leather shoes:
I like the contrast between the jet black shoes and the slightly lighter (and flat) laces. What do you guys suggest/recommend?
