As temperatures rise, celebrities are ditching basic sundresses for a more edgy and streamlined choice: jumpsuits.

Jumpsuits were all over the Spring 2012 runways, with designers like Derek Lam, Stella McCartney, Adam, Altuzarra and Diane von Furstenberg sending out an alternative silhouette option for warmer days.

Whether it’s sleeved or strapless, loose or cropped, the key to nailing this trend is all about proper tailoring.

Nicole Scherzinger opted to go nautical in Monte Carlo. Cameron Diaz balances out a long hemline with a perfect-fitting strapless bodice, wearing Stella McCartney at the ‘What To Expect When You’re Expecting’ UK premiere.

Cassie cinches her loose-fitting Salvatore Ferragamo Spring 2012 while stepping outside the Martinez Hotel in Cannes with a simple tie-belt, accentuating her waist and giving a more casual vibe to a wild print.

Over the past few weeks, we’ve seen the one-piece look pop up almost everywhere, from glamorous Cannes Film Festival ensembles, as seen on Eva Longoria wearing Elie Saab during a guest appearance on ‘Le Grand Journal’, to casual travelling gear at the airport, a la Diane Kruger, who arrived in Nice wearing a comfortable black number from Anthropologie.
