Best Seller: Marc by Marc Jacobs Totally Turnlock Percy Messenger Bag

Summer is just around the corner, and with Summer comes long weekends, vacation, and more time spend generally tripping around town. You really need to trade in your heavy work satchel for a smaller, more lightweight cross-body bag. After your fourth hour at the farmer's market, your shoulder will thank you.

Want a bag your inner fashion diva will appreciate as much as your worn-out shoulders? Check out this best seller from online boutique ShopBop. The Marc by Marc Jacobs Totally Turnlock Percy Messenger Bag is perfect for carrying the necessities while out and about. With Summer coming soon, it's really no wonder it's on the current best seller list.

The logo turn-lock closures keep the front patch pockets secure, yet accessible for grabbing your lip balm on the go, and the detachable strap means this cross-body can do vacay double-duty as a chic clutch. It comes in four colors, but the bright green Spinich color pictured here is by far my favorite.
