i don't know much about these things and never really paid attention before but maybe some of you ladies have

the 4 groomsmen will rent tuxes and match each other and they will have vests/ties that match the bms
I've seen that the groom can wear a different color vest ... can he wear a different style tux? would anyone even notice if the guys have one button jackets and he has 2 buttons?
also, would anyone notice if one dad was in a tux and one was in a suit? as long as they're both black?
the tuxes look just like suits to me (they're not the long jackets or anything) and they're all doing ties not bow ties.
i'm amazed how much the guys are worried about matching each other! my dad is totally stressing the groom's dad will look "fancier" than him if he only wears a suit and his dad's in a tux!
thanks
