i'm doing sort of a black theme too - black bridesmaids dresses and both Mothers in black. but all the flowers are bright pinks, purples, blues and greens. we are doing black table cloths too - to make the flowers and all the candles really pop!
i was in a black and white wedding in March, and i already wore the dress again 2x. i think my girls will also be able to wear theirs again. in fact, i might borrow it from one of them - i love the dress!
I've decided on using Black for my May wedding. The dresses are tea length and black w/turquoise accents. I saw the sample in black w/fuchia and thought it was nice, but I'm more into the blue colors. It's a Bari Jay dress #713. My reason for using black was that I wanted them to be able to use the dress again and I've been in several weddings and never once was able to use the dress again.
Edited to include a photo of the sample dress I saw...
