For many it is the decade style forgot, but erase disturbing images of ABBA wearing matching Lycra jumpsuits from your mind and remember that this was the era of Studio 54, Woodstock and the DVF wrap dress. Disco, boho or ladylike, SS/11 is all about the 70s – and where that decade is concerned it’s very much a case of the bigger the better. So prepare yourself for big hair, big hats and even bigger platforms - plus some incredibly tiny hotpants - and that’s just at Marc Jacobs! Elsewhere, House of Holland have channelled Halston with a collection of super shiny metallics, whilst Topshop Unique have perfected the festival look of the summer, which is more than a little reminiscent of Stevie Nicks. Think ethereal swathes of chiffon toughened-up with a fringed suede waistcoat, leather boots and lots of ethnic jewellery. There really has never been a better time to raid mum’s wardrobe for a vintage floral peasant dress - the likes of which dominated the catwalk at D&G. You can clash your prints and colour block your brights all you want, but the trend for all things 70s is guaranteed to win out in the end.
