This is probably an obvious question, but I am completely fashion/etiquette oblivious. We're having a very casual outdoor wedding, so the guys are all just wearing nice shirts and ties. I'm debating having my hubby-to-be dress a little differently from the groomsmen. If I do that, I obviously want him to be dressier than them, not less dressy. So here's my question - what is generally considered to be dressier? White shirts or colored shirts? Should I have him wear a colored shirt and them wear white, or the other way around?
