Pippa Middleton looked stunning in a custom Suzannah gown at the ParaSnowBall held at the Fulham’s The Hurlingham Club in London on Thursday night. The 32-year-old glammed up for the night at the Winter Wonderland-theme event which was hosted to raise funds for disabled skiers.

Pippa was the belle of the ball in her custom floor-length gray gown, designed by her favorite brand Suzannah. The dress featured a structured, sleeveless fitted bodice and a soft pleated skirt. The custom Roma gown had an additional feature, an embellished collar in black and gray.

It also featured cut-out detailing in the shoulders and peplum waist. Inspite of the demure design of the gown, Pippa showed off her athletic figure in the confection. The brunette beauty, who is back with her ex-boyfriend James Matthews, supported paralympians in snow sports. The event was organized by the Parasnowball by Disability Snowsport UK.

The columnist kept her long brunette tresses sleek and straight, tucked behind her ears. She accessorized with a silver watch and matching silver drop earrings in keeping with the icy gray or silver theme of the ball. Pippa also carried a small black leather clutch bag with a silver chain.

Her make-up consisted of a slick of nude lipgloss, matching blush, and some bronzer for her face. The health freak flaunted her brown manicure and wore black mascara and matching kohl-lined eyes. Kate’s younger sister looked happy and relaxed at the event, posing for a picture with the Chief Executive of Disability SnowSport UK, Fiona Young and chatting to coach Mike Dixon, and Crystal Ski Holidays representatives Tamsin Todd and Mathew Prior before speaking on stage.

Tickets for the ball cost 185 pounds ($270.25) and the cause was clearly close to the avid-skier’s heart. Pippa completed the world’s longest downhill skiing race in Switzerland attaining 67th place out of 105 competitors in January.
