For my wedding colors I am thinking of doing a light pink and a buttery yellow, with the bridesmaid's dresses being light pink. However, I don't know what color my mom and my fiance's mom should wear. I don't think either of them would look good in yellow and I don't want them in the same color as the bridesmaids. What colors could I put them in that wouldn't clash with the colors I've chosen? Thanks for any advice!
