Carry a woven clutch bag by Bottega Veneta like Lauren

Lauren Silverman got all dolled up for charity when she attended a fundraising event in London. Draped in a classic strapless black gown, the brunette beauty accessorized with a pair of diamond drop earrings and a Bottega Veneta bag.

The Italian brand is known for their woven styles so Lauren's clutch was instantly recognizable. The satin fabric gives it a luxe feel and we love the signature knot closure.
