I desperately need a handbag for my holiday. I'm going on a fancy cruise so there will be a lot of sightseeing and all day tours. The bag needs to be big enough for me to keep my purse, a bottle of water and a few bits and bobs in it. I prefer cross body bags, just easier to carry all day. I'm quite tall so the strap needs to be quite long. My holiday wardrobe is very bright coloured 
so the bag needs to be quite neutral. Not asking for much, am I?
I've been off sick for a couple of weeks now and I swear I looked at every website I could think of. NOTHING.
Budget is approximately £100 but negotiable...
Any ideas?
TIA
