Clutch bag??

Brides may have one but don't really carry it on the day, its given to a bridesmad or Mum to look after.

Its worth remembering that on the day you will already have your hands full, one hand you will have your flowers and in the other will be a drink or your groom/bride and when they are not there you will be grabbing a handful of dress to negotiate some steps or a puddle.

If you have a groom then he will have nice pockets to carry your phone or camera for you. Lipstick for tops up, as Sarah says - Mum or a bridesmaid. If I do see a bag around then its usually the draw string pouch type so you can hang off a wrist.
