Ex-Spice Girl Geri Halliwell makes us do a double take. At 2002 Oscars (left), last night in London (right). Photos: Ferdaus Shamim, WireImage | Dimitrios Kambouris, WireImage

At last night's Breast Cancer Care event in London (left), Geri Halliwell of Spice Girls fame wore a plunging purple halter dress that, shall we say, highlighted the focus of the night.

But it wasn't the first time Halliwell wore the low-cut, iridescent gown.

She also wore it to the Vanity Fair Oscar after party in 2002 (right).

Hey, if Anna Wintour can recycle dresses, then anyone can.

Kim Kardashian arrived at the Teen Choice Awards on August 9, 2009 in a little white Stella McCartney dress. Back in April, singer LeAnn Rimes hit the 44th annual Academy Of Country Music Awards in the same getup--but the country singer went for black, instead.

Angelina Jolie made her leather-clad return in this black strapless Michael Kors dress paired with strappy Dior sandals at the Los Angeles premiere of "Inglorious Basterds" on August 10.

Elle Macpherson took to the streets of Manhattan to film "The Beautiful Life" on August 11 in this gray Victoria Beckham "Carmontelle" sheath. The model-actress finished the look with huge sunglasses and pointy toe pumps. But Victoria wore the same cashmere-blend dress to shoot her Fall 2009 ad campaign in London, England on July 23. Her "posh" look included dark shades, her signature pout, and sky-high heels.

The True Blood star finished her look with a chic updo and Jimmy Choo slingbacks.
