Braidsmaids

I`m not sure about other countries, but in the US this is the *traditional* order of the processional:
(Pastor/Priest, Groomsmen, and Groom are already in place at front of church/venue)
Bridesmaids Enter (One by One)
Flower Girl & Ring Bearer (Enter together or one by one)
Bride and Father (or other escort)
On the Recessional:
Bride and Groom Exit
Maid of Honor and Best Man
Flower Girl and Ring Bearer
Bridesmaid #1 & Groomsman #1
Bridesmaid #2 & Groomsman #2
Bridesmaid #3 & Groomsman #3

Now of course you don`t have to follow tradition. It`s your wedding, line up your processional how you wish!

Good luck!
