My wedding is September 12, 2015. I also asked my bridal party as soon as the ring was on my finger. That, I'm finding was a HUGE mistake on my part. My fiancée wanted a big wedding and I told him to pick his guys and I would pick my girls to match. He chose 8 guys, his 3 brothers, my 3 sons and 2 very close friends. My girls have been fighting since we picked dresses. They absolutely hate each other and it has stressed me to the point I am seriously ready to elope. I don't want to elope and neither does my fiancée but the stress of the bridesmaids fighting is overwhelming. So my advice to anyone would be wait until the date is closer and make sure its clear that there will be no fighting or drama.
I knew who I wanted in my bridal party right away, but I wanted to do something nice to ask them, as I am one of the last of my friends to get married! I had a card created for each of them, that featured a picture strip on the front of every girl in my party (7 bridesmaids, one MOH), with a little verse I had written inside, asking them to be part of my party. I mailed out the ones to my long distance friends first, and gave them out in person to those I knew I would see within one month of getting engaged!
They were a big hit:) It's a nice small keepsake.
We were pretty lucky in the fact that we didn't have to really ask anyone. I am having my 2 best friends as co-MOH and my FI is having his 2 best friends as co-Best Men. We've known our whole lives we would be in each others weddings so it was a give in!
I plan on asking this September on the day we're getting married.
