Of course you wouldn’t cut in during the newlyweds’ first dance, but there are some less-obvious ways you might take the attention off the people who deserve it most. So ladies, don’t wear white. Even though it’s an old, slightly silly rule, other wedding guests will be pointing and staring at you, instead of oohing and ahhing over the bride, a woman who likely wants to be oohed and ahhed over. And don’t wear anything too revealing for the same reason. Also, avoid being too flashy on the dance floor (as in, don’t do the worm in the middle of a circle of bridesmaids) and getting on the mic to deliver a toast you weren’t invited to give.
