Wedding ceremony entrance order

This depends on your preference. We had DH's daughter walk down the aisle to light the candles, then his dad escort his mom down the aisle to their seats. I didnt have family there but if i did this is when the bride's parents woukd be seated. Next was the minister, best man and DH and they came in from the side. Then came my 3 BMs, 3 flower girls and my ring bearer and then me.

Mother of the groom (and her husband -groom's father)

Mother of the bride.

Groom and groomsmen- whether they walk the aisle or enter from the side

bridesmaids

MOH if you have one

ring bearer

flower girl- is always the last before the bride

bride and her escort (could be her Dad) if she has one

We are doing my mom and step dad (FH isn't inviting his mom and his dad has passed) then groomsmen, best man and groom down the aisle. If he changes his mind and invites his mom then she will walk down with him or her eldest grandson who is the best man. Then will be the bridesmaids, MOH and 2 flower girls. My son insisted on being the ring bearer and walking me down the aisle so we are going a little off tradition for that. I've been to weddings where the bridesmaids and groomsmen walked down together or both just walked around to their sides and sat in the front row so I'd say do it however you are comfortable.
