Pippa Middleton dazzles at the Sugarplum Ball in London

Pippa Middleton commands attention as she attends the Sugarplum Ball with boyfriend Nico Jackson.

Pippa Middleton left the conservative outfits to her sister the Duchess of Cambridge as she headed out in London for the charity Sugarplum Ball on Wednesday.

The beauty turned heads in a floor-length sheer gown which featured highly-embellished embroidery, but made a concession to plummeting temperatures in a sequinned crop jacket.

The 31-year-old was joined by her boyfriend, stockbroker Nico Jackson, who was suited and booted for the fund raising event in Mayfair.
