Fiance is having a best man, his father, as his only groomsman. Does that mean the only men in the wedding who will need to coordinate menswear are father of the bride, best man, groom? We're doing khaki suits & ties. Is it best to have all 3 men buy new suits or rent them? I'm guessing I can't just ask them all to wear the khaki suits they have now bc they won't look cohesive? Clearly I have no idea about this menswear business etiquette! Help please
