Are you a chronic bag switcher? If so, a purse organizer—a removable pouch where you can store essentials like keys, cell phone, and wallet—makes it a lot simpler to do the daily transfer. Try the medium-size Cherry handbag organizer ($26; goneshopping.ca) shown here in a leather Longchamp bag ($480; longchamp.com). In a pinch use a roomy makeup bag instead.
