My wedding colors are black and yellow. I've recently really started liking gray/black/yellow. My bridesmaid dresses are black and they're wearing yellow shoes. Initially I thought the groomsmen would be wearing black tuxes, but now I'm thinking maybe gray would look nice? Is it ok for them to wear gray tuxes since my girls will be wearing black dresses? I was thinking maybe gray tuxes with black vests and yellow accents. I have a really hard time picturing all of this and I'm a visual person...I need to see it to know what it will look like. Thoughts??
