I found when travelling in different countries using my drivers license for id just didn't cut it and I was forced to bring my passport with me to clubs and pubs. A document I couldn't afford to lose because I got too drunk and left my purse somewhere. Plus I hate lugging a purse around anyways so I ended up using this solution even after I returned home!
No more pick pocketing or being held up, or forgetting anything. Works a charm. You don't even really need to know how to sew well.
Step 1: Purse Pocket
Go to your local thrift store and pick up some old purses, or if you have any lying around thats even better. Pockets just large enough to fit some cash, passport and credit cards.
Step 2: De/Restruction
Cut out the inside pocket and sew it into the insides of the bottom of your fav pants or skirts.
Step 3: Fini
Et Voila! You're ready for a night on the town, that lets be honest, may turn into morning.
