DALLAS, Mar 15, 2011/ FW/ — One, Roberto Cavalli does not need an introduction. Two, his apparel line and accessories line are just to die for. Three, Roberto Cavalli is such a celebrity favorite that this week, we had two sightings and they are on either side of the Atlantic.

On March 12th, at The Mandarin Bar, Las Vegas, NV during the Vegas Magazine’s Spring Fashion Issue party, EMMANUELLE CHRIQUI wore a Roberto Cavalli snake printed gown.

Two days later, on March 14th, in London, ELLE MACPHERSON was spotted carrying a Roberto Cavalli Diva Bag.

Speaking of London, The Bieb kicked off the UK leg of his MY WORLD TOUR and rocked his custom made RONAN leather studded letterman’s jacket and high-top sneakers! Styles similar to Justin Bieber’s custom made letterman jacket will be available for Holiday 2011.

RONAN, which launches this fall, offers denim and apparel for men and women who are bold enough to express their own personal style.

From the creative masterminds that brought you Rock & Republic, the versatile denim and leather collection blend wearable, wardrobe must-haves with quality materials and expert craftsmanship.
