Activity for Ariana

I have a male bridesmaid, or Bridesman, as we're calling him. I want to get lavender colored satin robes for all my "girls" but with him, I'm stuck. He's said he will wear whatever I get, but I don't want him to hate it and feel uncomfortable in it....

I need some advice from people going through the same thing. I'm having a real hard time determining what our seating chart is going to look like, and right now I'm trying to tackle the head table part of it. I've pretty much decided on a sweetheart...
