Solange Knowles jetted to Vegas to hit the 1s and 2s for a Roberto Cavalli trunk show and  “Black Is Never Absolute” photo exhibit at the designer’s freestanding boutique in Crystals at CityCenter.

The DJ rocked the house in a silk Cavalli (of course) maxi dress that she loved so much she had to tweet about it: “Dj'n the Roberto Cavalli trunk show in Vegas. Wearing a dress I don't want to ever part with.”

Solange’s outfit's floral detail may have been inspired by one of the photos in the exhibition, as Cavalli explained “My prints are always the result of my photos and are the foundations of my clothes ... The most normal object has the ability to stir distant memories in my mind and become a source of inspiration for a collection or even a simple detail on a dress.”
