Possibly "trying too hard" ?
Lets say you have a brown belt, brown shoes, would it be bad to then go get a brown/tanish colored tie?
Instead of this being matchy/matchy, I think it is more a function of the fact that brown shoes are the only appropriate choice if you wear a brown tie, and the belt then matches the shoes. Maybe it's just me, but I cannot imagine wearing black shoes with a brown tie. BTW, love the fit.
