Last night a star-studded party for Roberto Cavalli’s 40^th anniversary took place to kick off Paris Fashion Week. Celebrities flocked to the event to join in the celebrations for the legendary designer.

As can only be expected the only designer of choice for the evening was of course Roberto Cavalli. The show-stopping dress of the night went to Leona Lewis who wore an orange (yes I know but it kind of works) ruffle bottom ball-gown.

Taylor Swift arrived in a Cavalli little black dress. Rachel Bilson showed how chic leopard print can be in a strapless gown from the pre-fall collection. Bar Rafaeli chose a backless design from the archives (as seen on VB), whilst Aishwayra Rai wore a silver gown adapted from last years resort collection. Finally Heidi Klum wowed in a nude draped design.
