Now that London temps have dropped to below 70 degrees, Pippa Middleton is upgrading her wardrobe from breezy sundresses and casual wedges to a sleeker look.

The 28-year-old stepped out in a teal Diane von Furstenberg dress, black blazer and chic booties on Wednesday. She rocked a sleek ponytail instead of her usual loose waves and carried a black studded Tabitha bag -- an outfit that could be considered almost too-trendy for her current gig at a geothermal energy firm in London.

On Thursday, she went for a sexy lace shift dress from H&M, which she paired with another black blazer, tan Lamb1887 envelope purse, matching ballet flats and Gucci sunglasses.
