The spring/summer edition of Milan Fashion Week, which began on Wednesday and runs through this weekend, was up against it from the get-go. It followed a rejuvenated London Fashion Week, which was buoyed by Riccardo Tisci’s Burberry debut. And it will be missing Gucci, one of its leading lights (which this season is showing in Paris). Nonetheless, Milan’s luxury houses know how to put on a memorable show. On Thursday night, following a dynamic Prada event held inside a new concrete-clad space at Fondazione Prada, Emporio Armani took guests to a hangar at Milan’s Linate Airport. Models walked as Alitalia planes took off from an altogether less-sparkly runway, and the show was followed by a Robbie Williams performance. It’s not over yet for Milan: look out for this weekend’s Missoni and Giorgio Armani shows.

North Londoners may think that heading south of the River Thames is a thankless transport mission but the opening of the South London Gallery’s annexe will encourage them to make an entirely worthwhile trip. Taking over a former fire station on busy Peckham Road, the gallery’s extension opens its doors today to reveal a sensitive refit courtesy of 6a Architects – as well as an exhibition on humour in contemporary art, titled Knock Knock. Other than providing four new gallery spaces, the Fire Station also features a studio for artists in residence, an education room used by the school across the road and a kitchen that can be hired by artists and the public: proof that any gallery opening in this rapidly gentrifying area needs to keep connected to the neighbourhood that surrounds it.
