Prorgram question

when you list the bridal party, do you list them in alphabetical, or in the order they are walking out in?

I have two separate sections, one for BM and one for the GM underneath.

So it reads:
Bridesmaids:
Valerie ___
Erica ___
etc
etc
etc
etc

then
Groomsmen:
Phil ___
Michael ___
Vito ____


Should they be in the order they walk out to or alphabetical?

I listed them by order of importance/relation. MOH/Sisters first...then cousin...then in-laws...then friends.

I guess I am no help!

I listed order they walk out.

ETA:
I did all bridesmaids (in order of walk out)

then a separate section for bridesmaid
