If groom will be wearing a Old Hollywood Glam tux (black pants, white jacket + shirt with black bow tie)...is it okay for the rest of the guys to wear a black suit? We're not having something super formal but just like the old vintage look. Wasn't sure if they had to have a tux or can they wear a suit instead for comfort.Is that weird? Also... the girls are all wearing different dresses/lengths/shades of deep purple. Should the groomsmen wear the same suits/tux or should they wear their own stuff they own?Please help!
