Lilly Becker sports beer maid-inspired dress at pre-Laureus dinner

London -  Lilly Becker, who is the wife of former tennis pro Boris, wore an odd frilly dress at a pre-Laureus Awards dinner on Sunday.

The Dutch model, wife to former tennis pro Boris, looked like she should have been at Oktoberfest, not an exclusive pre-award show dinner at Mayfair's Cipriani restaurant, the Daily Mail reported.

The frilly outfit was remarkably similar to a traditional German dirndl, apart from the fact it was made from black leather.

It had off-the-shoulder sleeves as well as thin black straps and a cut-out patterned front.

The attire was cinched at the waist with elastic and had an asymmetrical hem with more small cut-out shapes around the bottom.

Mother-of-one Lilly teamed the ensemble with black tights and nude and black heels.

The outfit bore resemblance to the white and red dirndl Lilly wore at Oktoberfest with Boris in 2007.

She later covered up in a leopard-print fur coat as she left the venue with her husband.

Boris, 44, sported a blue pin-stripped suit with a colourful scarf in the front pocket.

Georges Kern, chief executive of watch manufacturer Roger Dubuis was the host of the event.
