Ladies I need some help! My FI thinks it is totally acceptable to go find his tux and the tux for the guys in March...our wedding is in April! I know that we don't need like 6 months like we do with a dress but my only concern is that 3 of the 5 groomsmen do not live in the same state as us and it is going to require some coordination to get this thing done right. What is a reasonable amount of time to do it in advance?
