LOL. Yes, I totally agree with you. It is flashy!
I am just a guest, but it's my first cousin's wedding. And at our Assyrian weddings, immediate family members have to dress up like that... as if we're going to prom (other guests do, too! lol.) So I wouldn't look out of place. Everyone gets all "ducked" out so to speak. It's lots of fun.
But I see where you're coming from, totally! You didn't offend me. *hug*
