I'm having my groomsmen wear light pink ties to match the bridesmaids. Their tux will be a dark charcoal grey. At the shop, my fiance and I preferred the matching light pink vest, but the groomsmen liked the black vest (they didn't have an exact matching charcoal). I honestly think the groomsmen just want to avoid wearing pink regardless of whether it matches or not.
Do the groomsmens' ties have to match their vests?

Pink vest and tie:
Above are pictures to help you visualize what they might look like in pictures. No, the vests don't have to match the coloured ties and some people think it looks better when the vest is the colour of the suit itself instead of the colour of the tie.
