I’ll vouch for that.
My rule of thumb (no idea how correct it is) is that, because suspenders have leather anchors coming off the fabric parts, I match the leather to my shoes. It doesn’t have to match exactly, but brown-anchored suspenders go with brown suits and black-anchored suspenders go with grey or black.
I started wearing them because I tend to be an old-fashioned dresser anyway, and I’ve gotten nothing but compliments. They tend to project confidence, at least in my estimation.
I’ll cop to the fact that I picked up the look from one of my law professors, who always looks incredibly smart, confident and pulled-together in his very conservative stylings… but then, you’re in the legal profession, so for the purposes of this advice I could have jacked it from someone much, much worse.
