We have 4 each in our Bridal Party. Sadly we lost our Best Man last April due to heart failure at 30. It was terrible. We have 3 friends each from our childhood and I have my sister and he has his brother. Luckily all of my party grew up together so we have all been friends forever!
I'm actually only having one, my Maid of Honor. It was either that or 10! My fiance wanted to have all of my brothers, his brother, and all his childhood friends as a part of his half of the party, and I don't know that many women! So we settled on just the Maid of Honor and Best Man
I have a total of 4, with one being the Matron of honor. I can see how six is a lot, but it's really not! My cousin had about 9 girls though lol. You can also have one matron of honor and one maid of honor.
We have 7 on each side. I always wanted a lower number, however my fiance thought otherwise and wanted around 10 on each side. We compromised on 7 and I'm going crazy with keeping up with everybody!
