I rarely use cash. I often carry some cash just in case. But instead of keeping it in my purse I stuff it into my bra. Its mainly the left side that I hide things in but; if I'm hiding or wanting to keep up with a couple of things at once I use both sides. I have put my cell phone, lighter and money in my bra for safe keeping. If I am going to a bar and I know I'll be dancing all night I'll stuff my credit card and my cigarettes and lighter in there. The money is usually folded and placed into the plastic wrapper of the cigarettes.
I'm a new bra carrier due to the fact that I've always been smaller up top than larger girls. Within the past couple of years I've gained 10lbs and my bra size has increased. I like the new me (up front), my beamers are getting brighter lol.
Bras are better than purses when you're traveling light.
