Gearing up my undergarments for Paris

Typical French Maid costume, available at brasNthings.com

The bra for my upcoming Paris trip will be a regular, everyday bra, nothing special ... except it may have something attached to it. OR maybe it will be attached to my panties. You will never know.

The "it" I'm talking about is this ...

... a flesh colored "Secret Stash"TM detachable bra pocket. I'm going to try out my new undergarment gear when I get dressed for an evening soiree that I am attending this weekend. I'll stash my driver's license and emergency cash in it.

I've read about the problem with pickpockets in European tourist zones, and decided this would be one plan of attack to ensure the safety of my financial instruments. I'm not inclined to carry some kind of "anti-slash," theft-proof travel purse, and would rather use a nice leather cross-body handbag when I go on my trip. (Hey, I've travelled all over New York City, on the subways and along the crowded streets; I know how to guard my belongings!)

I've searched online and seen the bags that have zipper locks and shoulder straps reinforced with steel cable wires, but I haven't found an attractive one that suits me.

How about you, what have you used/what do you suggest in this regard?

French related bra trivia:
"Bra fashion history truly began with the first bra to be patented. The first bra was patented in 1914 by Mary Phelps-Jacobs an American. It is not thought to be the first bra ever, but it is the first patented record and that gives her the credit. Mary Phelps-Jacobs patented her bra design under the patent name of Caresse Crosby. Some suggest it was her French maid who provided the idea or the stitching help. Two silk handkerchiefs were tied together, baby ribbon sewn on to make straps and a seam set in the centre front."

Until Paris ...
