For the past two years I have got used to the 'waist wallet' in which you can carry money, TCs, Cards, ID, etc. Millets do one which is slim and yet has several compartments for the stuff. It looks very neutral and can be used by either sex. It is also very handy in busy airports etc where you have lots of luggage but need quick access to your travel documents.

I found this particularly useful on our recent trip to Orlando.
