The Continental Sidekick was invented out of need—and boy do we need it! The small-scale leather zip bag with detachable billfold works as a wallet, clutch, or cross-body purse while holding all your various and sundry essentials. Because nobody appreciates a bulging evening clutch, Bevée bags was co-founded by Seattleite Sasha Muir (best known for founding nail polish empire Butter London) in response to a hole in the market for small, versatile yet luxurious bags. It might be the smartest-looking and smartest-working purchase you make this fall. $195 at Bevée.
