Demi Moore was the first to wear this one sleeved Lanvin Spring 2010 dress nearly a year ago in October 2009.

She added a stunning necklace, a black clutch and black Lanvin ankle strap heels to her dress which she wore to the 2009 Freedom Awards.

Jennifer Lopez wore this dress is a gorgeous chocolate colour she arrived at the Neon Charity Gala in Moscow, Russia back in May.

She also opted for a statement necklace, Christian Louboutin clutch and Sergio Rossi heels.

Catherine Deneuve wore the dark grey version of the same dress when she attended the “Potiche” Premiere during the 2010 Venice Film Festival on Saturday.

Her necklace doesn’t make quite the same statement as Demi’s, as she also teamed her dress with a black clutch and black peep-toes.

Surprisingly Pace Wu wore the same dress on the same day as Catherine, but in a different colour.

The actress wore her taupe coloured dress to the “Bulgari And W Magazine Party” at the Hotel Cipriani in Venice on Saturday night.

She wore the same Lanvin ankle strap heels as Demi but Pace opted for the nude colour.

A Nina Ricci satin clutch and a multi-coloured beaded necklace completed her look.

Pace may have gone head-to-toe runway, but she looks far more elegant in this dress than Demi and Catherine, so she wins for me.
