Dignity. It’s pretty overrated when you’re after something you really, really want.

Hit the Billion Dollar Babes sample sale, and you won’t have any left at all. None. Niente. Just a great big smile on your face and a hunger for more, more, more.

Billion Dollar Babes holds sales all over the U.S. — New York, San Francisco and L.A. (where, like a true A-lister, it premiered on Sunset Strip) and now it’s coming to London. Up for grabs: clothing and accessories by designers such as Temperley, Amanda Wakeley, Philip Treacy, Issa and Missoni, with prices at wholesale and below. There are even changing rooms and a staff of 60 on hand to help.

Bring your spikiest heels (for stomping on feet) and bulkiest handbag (for beating rival bargain hunters out of your path) and get ready to shop.

Just make sure you’re wearing presentable knickers.

You know how communal changing rooms can be.

Porchester Hall, 45 Porchester Road, Bayswater W2. June 25, 8 a.m.-6 p.m. Admission: £2 (benefits Fashion Targets Breast Cancer). RSVP a must: billiondollarbabes.com.
