Any day is a good day to dress up like Kate Middleton — though some looks are more accessible than others. Fortunately, her latest look while out at a Sportaid athlete workshop in London happens to be one of the easier styles to re-create: a polished, play on denim (J Brand, to be exact) that's begging to be worn on a crisp Fall weekend. So, pull out your blazers and striped tees — or click below to find one just like Kate's — to re-create the Duchess's preppy look. Hers was completed with Stuart Weitzman wedged pumps
 that would make a perfect brunch-to-dinner ensemble to live in all Saturday or Sunday (and really, any day of the week).
