Fashion Math: The Seasonally Challenged Edition

We're not exactly newbies in summer-to-fall dressing — and yet, every year, navigating this tricky, transitional season is a challenge. What to wear to work when it's not quite sweater weather? How to dress for a hot date and avoid that night-air chill?

Luckily, we've got the perfect solution: the Banana Republic Issa London Collection. The new collaboration between our favorite, better-than-basics brand and Kate Middleton-approved Issa London makes looking chic beyond easy.

To prove it, we took two of our favorite fall trends — the work-perfect wrap dress and the mod twinset — and put together four chic outfits that have you covered for fall and beyond. Whether you're going for that big promotion or heading out on the town, read on for a major dose of wardrobe inspiration. Trust us, fall dressing's about to be as easy as one, two, three.
