I just want to throw this out there for any newly engaged brides who are choosing their wedding party. If you have guy friends/family or your FI has female friends/family who you would like to be in the WP, please consider making them bridesmen or groomswomen. I really, really wish I had done this. There are so many stupid situations that can be avoided by just putting people on the side of the person they "go" with, regardless of gender.
I hope someone learns from my mistake!
