The bag: The Row Python Shoulder Bag ($5,100)
Why we love it: After taking home the CFDA prize for Womenswear Designer of the Year, Mary-Kate and Ashley Olsen have proven their collections are worth investing in. This dressed-up take on the structured satchel is just one of the many covet-worthy items The Row has to offer, but it's up there on our list. The shape makes it a classic, while an exotic finish sets it apart from the rest. And whether you're dressing up or dressed down in jeans, there's no occasion this bag can't handle.
