First, It's your wedding, do what you want. Second, if your worried about keeping your bridesmaids happy, black dress with pink ribbon may be a better choice as a pink dress may not look great on everyone, and black is universal. Either way it will look great.
Black with pink if you have the choose.. I think the other way around would be a little much....
I agree - black is pretty classy and can be sweetened with pink accents. Pink dresses may be a bit too little girl for your ladies.
