So I need some advice, because its been something that has been bugging me. My FI has decided he and his groomsman will wear white button ups and khaki dress pants (beach wedding). I have been trying to find something that we like, and that will fit my FI, needs tall size. Do you ladies think all the guys need to wear the same shirt, same brand? Can I tell them all to just find the shirt of their choice? I was already planning that for the pants. Any thoughts?
