(X-Post from BHB) What color dresses should I use? w/Pic & Poll

For my BM's boquets I'm using roses & cala lillys in champaigne, pale pink and light pink (somewhat 'similar' to pic below). The flower colors are a definite but now I'm torn for the color of the dresses. My wedding is in May at VYC if that has anything to do with what you'd choose. I also want Tiffany Blue included 'somewhere' because that's my favoritest color and I need it in my wedding Thanks so much guys
