Pippa Middleton made an appearance at the BGC Annual Global Charity Day in London today, where she turned heads in a fashion forward jumpsuit. For the philanthropic event, the brunette beauty wowed in a gray Reiss onesie ($37, reiss.com) that featured a relaxed fit, slightly tapered leg, functional zip detail at neckline, and contrasting top layer. The recently engaged star styled the chic number with sleek coordinating suede pumps and a pale blue leather clutch bag. Middleton completed her ensemble with a pair of diamond stud earrings and her massive engagement ring, which she showed off while making phone calls for the charity. The royal-in-law styled her long locks and in loose waves and added a touch of rosy pink blush to her cheeks that highlighted her beautiful freckles. A pretty lip color finished off her beauty look.

The 33-year-old celebrated her birthday last week while wearing a monochromatic ensemble made up of cropped tailored trousers, a matching blazer, and cute wedge sandals.
