The Mata Hari Tayla iPhone Pouch ($64) is a handy accessory that pops. Red leather already has us tethered - add velvet lining, a built in mirror on the inside flap closure, and a tassel keychain to this guy, and our heart rate quickens. Not on-the-go? Take off the detachable shoulder strap, and stick it in your purse. Versatile style 101.
