I Don`t Want Any Bridemaids In My Wedding

Well, honestly I`ve never seen it done, but nothing says you have to have any number of people. You do need two people to sign as witness`s on your license and it usually is done by the Best Man and Maid of Honor. But I`m sure two groomsmen would do.
But I`m not clear why you want it this way. You say you have alot of friends and family that want to do it, and your fiancee` wants his friends, so why not have them. We only had Best Man and Maid of Honor because we were living out of state and moved form one state to another during our planning and thought it would be easier for everyone. All my friends understood, and were very helpful to my MOH when it came to my shower, and everyone went out for my bachlorette get together. Will you miss out on all these things.
Why don`t you want them? I would think you would want someone with you that day, helping calm your nerves, share your excitement etc.
Anyway to anwser your question if you have to have them NO you don`t, but I would really think about it and be sure about your decision, it is not something that you can change your mind about at the last minute. Good Luck!
