Zac Posen is darling. He posts flowers and food shots on Instagram, famously babysat “Girls” creator Lena Dunham as a kid (he’s still the only person who can dress her) and is almost too sweet the contestants on “Project Runway.” (We secretly miss bitchy Michael Kors.) No wonder the designer’s ZAC by Zac Posen handbag collection manages to be as chic and architectural as his runway collection, but with a down-to-earth vibe. Our fave this season: The Eartha double-handle satchel—an homage to Ms. Kitt, we must imagine—in caramel with black contrast stitching and hardware. It’s the perfect “pull it together, sister” staple for any weekend look. Just attach the optional crossbody strap for museum hopping, pumpkin picking, beer tasting and other fall adventures. Also available in black patent leather with shearling sides. $595 at Handbags in the City. 840 Aliceanna St., Harbor East, 410-528-1443. handbagsinthecity.com
