Blake Lively makes few public appearances (if you had Ryan Reynolds at home, would you?), but when she does, she looks spot-on. Case in point: her street style win yesterday in downtown NYC. Serena van der Woodsen (we're still going through Gossip Girl withdrawal, OK?!) nailed casual-cool in black overalls (need), sunnies, a cross-body bag and the pièce de résistance: flat oxfords. The ideal bridge between fancy stilettos and cool kicks, we've found our new shoe closet staple. See? Even red carpet queens give their feet a rest sometimes. 

Want to wear your overalls in the office? We've got you.
