If you are going to buy only one bag this season (we know you won’t, but still), make sure it can go with everything. Black and gold are the combination making a comeback this year in a big way. Whether your look is flirty, professional or casual, choose your weapon wisely. The Jimmy Choo Malena Satchel, $1595, is in durable nylon with gold-tone hardware and snakeskin-textured leather making it both practical and chic. Marc Jacobs’ Jen Satchel, $775, features an inverted pleat, gold tone zipper, closure and accented belt, making it the perfect complement for a sophisticated professional. The Chloé Kira Medium Satchel, $1795, is the hallmark of casual. The supple, washed calfskin leather is accented with fancy flap closure, removable shoulder strap, graceful gold-tone chain wraps and nail heads.
