While we've always been fans of Mary-Kate and Ashley Olsen's style [1] — even when they wore kerchiefs and frosted lip gloss [2]! — we must say: the twins' fashion designer outfits are the ones we'd live in forever. They somehow manage to find the balance between comfy and polished [3], pairing loose, breezy pieces with stuctured blazers and work bags.

So of course Mary-Kate would step out in the one shoe that perfectly embodies the best of both worlds, better known as Gucci's Princetown Leather Slipper. The cozy furry slip-on is what her style's all about, not to mention it pairs perfectly with the cropped wide-leg pants, beige blazer, and black tote she wore while out in NYC.

This look is one that would easily work for a casual Friday or the weekend. Read on to check it out in full, then shop the shoes you need to steal MK's styles.
