How much are your flowers?

I'm trying to figure out a realistic flower budget.

Can you tell me what you're getting and what you're spending?

I need 15 CPs (I'm mixing high and low)
2 bouts
2 bo-ks
2 mom coursages

I'm also considering some sort of chuppah even though I'm not jewish, but we're getting married on a rooftop and need some sort of altar decor.

Also, am I supposed to get my brothers tuxed up and bouts if they're not in the bridal party (side question, haha)?

Thanks!
