I'm planning a little holiday in March and I just realized that I have NO shoulder bags. Obviously this is a serious pain if you are on holiday and are walking around a lot. But I can't decide between the First, Twiggy, or Purse The First is my favourite Bbag style, but I'm concerned that I won't fit all my things in and you can only have 1 bag with the new security rules. So that leaves the Twiggy or Purse. What Bbag do you ladies take with you when you go on holiday? Which one works best? Thanks!
