I got a great coupon in the mail today for the guy's tuxes, when should I go in and figure out the colors with the store? Also, who generally orders tux's besides groom and groomsmen? I was thinking my dad, my brother (who's playing music for the ceremony), and our two ushers? The ring bearers are going to just wear pants and a white button down top so it's easier since they are both toddlers and grow so fast.
ETA: Neither of my fiance's parents are with us anymore or they would have been included.
