Calling on the etiquette police! FH and I are having a little debate and some input would be appreciated. We've seen the growing trend of requesting/suggesting guests wear a specific color to the wedding/reception (Beyoncé anyone?). FH thinks this would look great in photos and I agree about the photos but....Now we wouldn't ask that everyone go out and purchase a pink outfit, but rather "little/long black dress attire" thinking guests would already have something along these lines or if they had to purchase something they would likely wear it again. We are having an evening wedding of 50 guests, very close friends and close family only. However, I'm not quite sure how I feel about this. It doesn't sit right. Thoughts?
