My soon to be brother and laws girlfriend is good friends with me, but I already have a HUGE wedding party and pretty sure my mom would kill me if we added 2 more people (because we would need another groomsman too). She has always told me how much she really wants to be in my wedding and I would love for her to be, so I asked her to be my flower girl and she seemed super happy about it. I'm a little nervous about it because I don't want her to feel left out or offended, but it's all I could really do. Has anyone done this before (she's 23) and how did it go?
