I love those BM dresses, Alfred Angelo. I may be considering that dress for my BM. Im wearing Ivory and having Mocha bridesmaid dresses. I think your dress would look lovely with the pink, and the flowers too.

Im havind dusky pink wiv champagne/gold

Champange is good. a lot of color can match it.
