I just want to check I've got this right...
MoH duties = Bride asks MoH what sort of budget she has for a dress. MoH gives a max figure. Bride and MoH agree on a dress that works with the brides vision, and most importantly, makes MoH feel great.
MoH shows up (mostly sober) at the agreed time on the day of the wedding, walks down the aisle at the appropriate time, stands with the bride, and smiles for pictures.
BM duties = Bride asks each BM individually what sort of budget she has for a dress. BMs give a max figure. Bride and BMs agree on a dress that works with the brides vision, and most importantly, makes BMs feel great. (Can be the same dress, or not).
BMs show up (mostly sober) at the agreed time on the day of the wedding, walk down the aisle at the appropriate time, stand with the bride, and smile for pictures.
Even then, this is not strictly true, I guess... BM has an emergency the day before the wedding and can't make it on time, she'll be there for the reception if she can make it in time, maybe. Still a BM.
Flying out for a DW, one BMs suitcase gets put on the wrong flight and ends up on the opposite side of the world. Still a BM. Just turn up in whatever clothes you have/can get.
BMs are the girls you are closest to. People you can't imagine not having in your life, regardless of how often you do/not get to see/speak with each other.
MoH is the person you absolutely love most in the world (outside of family).
That sound about right?
