These two ladies' wallets are both made of black nylon with a silver clasp. They are both approximately 7" by 4". They both feature card slots, a zippered coin pocket, and bill compartments. However, one is $14.50 with shipping, and the other is $159.89, on sale. That's what the name "Prada" will get you: a 1000% markup. Go with Old Navy; I think their wallet is better looking anyway!
