Los Angeles-based designer Tracey Tanners wallets, come in leather or cork, measure about 7'' by 4'', so they're small enough to fit in your back pocket, but large enough to hold credit cards and cash. Inside, the wallets are lined with interesting materials (prints with skulls or flowers, for instance), while Tanner also makes bags, wristbands and t-shirts. You can find a list of stores that sell Tanner's stuff on her web site; Sirens & Sailors in Los Angeles and Cog & Pearl in Brooklyn both stock her goods. The shimmery gold wallet pictured here is $65.
