Just a tip I thought I would share for the gals that don't want to take a purse with them when venturing out (to the discos).
Take an old style glass case, the kind the glasses just slip in, and have a plastic clip on the side. Cut it just below where the clip is, roughly in 1/2. Take it to a shoe repairman and have them stitch where you cut it. You now have a mini pouch that can hold id, money, a small lipgloss, and room key!
I slip this into the underarm area of my dress/top and the clip stays on the outside. It is out of the way, easily accessible, and there is no worry of theft.
Hope this helps!
