Arrivederci To Milan Fashion Week

George Clooney rocks up at Armani, Roberto Cavalli celebrates the big 4-0 and the Dsquared twins show restraint (for once!) on the catwalk as Milan Fashion Week draws to a close...

Model moment: Natalia Vodianova made a triumphant return to the catwalk, opening Roberto Cavalli's 40th anniversary show in a sexy halter dress with thigh-high slit and cutout swimsuit-style top. To celebrate 40 years in the business, Cavalli sent 40 looks down the runway on the likes of Karolina Kurkova and Erin Wasson, with French model and actress Laetitia Casta flaunting her curves in the finale dress (see them all in the gallery below).

In the navy: Giorgio Armani's s/s 2011 collection took inspiration from the Tuareg peoples of the central Sahara, which translated into a backdrop of sand dunes and models clad in silk turbans and tribal jewellery. The whole collection was done in variations of deep blue, with a jacket for day (often paired with trousers and a sheer silk top) and countless variations on the dress for evening (draped, sequinned, jewelled and asymmetric). George Clooney and girlfriend Elisabetta Canalis sat front row looking chic in matching black suits.

Party time: Diane von Furstenberg was fêted by Italian Vogue's Franca Sozzani and Lapo Elkann, and guests including Jada Pinkett Smith and Mischa Barton turned out to celebrate the disco-loving designer. Pinkett Smith and Barton also attended the Ferragamo Seize the Moment Party at the headquarters of the Milanese stock exchange with Claudia Schiffer and Margherita Missoni in tow. Meanwhile, Bulgari toasted the jewel-toned capsule collection of bags that Matthew Williamson designed for the label, with Rachel Bilson and Carine Roitfeld.

Prep school: Gone was the fetish wear of past collections at Dsquared this season, replaced with a preppy sensibility down to the flat oxfords and geeky glasses. Twins Dean and Dan Caten toned down their look for spring, pairing khakis with button-downs and cardis over shorts. Even eveningwear was given a masculine twist, with variations on tuxedo-style jackets.

Happy 40th!: Roberto Cavalli, master of animal print, snakeskin and embellishment went all out in the extravagance stakes to celebrate 40 years in fashion (check out the gallery below to see more looks from the collection). Vixen after vixen stalked down the catwalk, with sleek, straight manes, wearing fringed and laced leather trousers, patchworked tops, cropped snakeskin jackets, crochet dresses and bead and crystal-layered chiffon gowns, revealing sexy bits of midriff and leg. The crafstmanship was as exquisite as the spectacle, and it was the kind of clothing you wouldn't be surprised to find in the tour wardrobes of front-rowers like Taylor Swift and Leona Lewis (who were also joined by Heidi Klum and Rachel Bilson).
