I am in Pred's wedding in October.
She doesn't really get into the whole picking-out-dresses etc thing,
so we are keeping it very simple with a little satin number from david's bridal for the 4 of us in the bridal party.

It will have a lavender grosgrain belt and lavender underlay that peeks out at the bottom hem.
Kinda like this (but the one piece halter dress and I couldn't find the underlay):

The debate is: SHOES.
She doesn't want gold, I don't think silver will go, so keep your eyes open for options or share your suggestions!.
I know this isn't inspiring, but be inspired by helping it not be a "27 Dresses" moment!
