Right now I've been planning on having my bridesmaids wear knee-length black dresses; picking them out themselves so that they will hopefully be able to wear them again. They would carry hot pink flowers.
I was also hoping that the greeter/guest book attendents could wear silver or gold colored knee-length dresses with a black sash or something like that to tie the look together.
My question is how formal should I make this wedding? I definitely want it to be a nice affair (semiformal or black tie). The biggest issue is that most of my family will underdress if I say semiformal. My sister has worn a denim jacket over top of a dress at a semiformal wedding and I am certain that most of the guys won't even wear jackets. I am mostly concerned about the denim jacket as she is not in the wedding party so I don't get to dictate what she wears, but also my other sister's wedding she wore a jean jacket and then walked around on stage behind the wedding trying to take pictures even though she wasn't the photographer. I don't want to confront her and say "hey listen semiformal means nice dresses and guys in suits, not a denim jacket", besides most of the guys in my family would still not wear a suit.
I might sound like bridezilla for worring about what my guests wear so feel free to call me out if that is the case. I just feel like a wedding is an important event and I don't want my family dressing down for it, especially because my FIs family will be paying for most of it and they want a big bash.
The solution I am thinking of is making it a black tie affair. I'm hoping that my family gets the hint and that even if they don't wear tuxes at least they'll dress somewhat nicer than business casual and won't tick off my FILs. I am also planning to have a family picture so I feel like what they wear is more important to me than what the majority of my guests wear.
So after the long explamation, my question is whether it is ok to have a black tie wedding if the bridesmaids are wearing cocktail-length dresses? I don't mind long black dresses for BMs although I really want something that they can wear again and I don't know where they would use a full-length black gown again (at least a knee-length dress they could wear to someone else's wedding).
