One thing that I've noticed over the years is that a woman will have a beautiful handbag, but her wallet is usually a disaster. Bulging to capacity with bills, cards, and old receipts, its lumpen shape circa 1996, that old wallet demands retirement, NOW.
Here's the perfect wallet replacement. Commes de Garcons wallets come in a variety of shapes and sizes (prices, too; some may be a bit too dear and are best as a "joint" gift). The colors are rich and make it easy to locate even in the biggest fumbler of a bag. And they're simply well designed. No more overstuffing. This forces some major editing, culling the unnecessary cards and paper flotsam invasions. Excellent.
So make them treat their funds with respect. Commes de Garcons wallets are available in all their glorious permutations at www.okstore.la.
