Less than a week after turning heads on the sidelines at the 2011 Wimbledon Championships, Pippa Middleton got back to business, namely looking hot while strolling through London.

The 27-year-old stunner, who was recently spotted packing on the PDA with on-again boyfriend Alex Loudon, stepped on in a chic black-and-tan striped silk dress under a quilted, cropped black leather jacket from Whistles on Wednesday.

And just like her big sis, Duchess Kate, who often rocks affordable labels, Pippa's two-tone dress is by BCBG Max Azria. Originally $248, it's on sale right now at for under $150.

Black wedges, her favorite Modalu bag and a Knomo laptop case completed the look.
