On the red carpet at the amfAR Inspiration Gala in Paris last night, Fergie wore Louis Vuitton.

When she presented Marc Jacobs with an award at the event, she changed into a look from the designers Fall 2011 collection – sans the cute polka tights.

The grey polka dot peplum dress was accented with a black waistband which gave Fergie the perfect hourglass shape.

She kept her hot red lips from her red carpet look, but opted to wear her hair down on this occasion.

Do we call this look ombre, or do we say Fergie desperately needs to touch up her roots?
