This weekend, Glastonbury is celebrating its belated 50th birthday, and over the past five decades, there are now several traditions that we can rely on each year. There will be a bit (or a lot) of rain, Paul McCartney, a lot of Hunter wellies and a sighting or two of Sienna Miller and Kate Moss. Today, Miller was photographed at the festival in two outfits that we think will go down in Glasto history. First, she wore navy-and-deep-red striped trousers with a red pinstripe overcoat. It was fabulously eccentric thanks to the clashing prints and looked amazing against the tents and festival flags. But the outfit that has really caught our attention is her brown linen minidress, which has spaghetti straps and an open criss-cross back.
We wouldn't think of wearing a fitted minidress to a festival, but Sienna makes it work perfectly with her glossy ankle boots and stacked gold jewellery. The best part about her look, however, is that it's a £50 dress from Mango and currently (well, when we last checked) available in all sizes. Her accessories are also perfectly pitched (sorry, we had to make at least one camping pun), with gold and pearl-detailed jewellery from Missoma and clear-frame sunglasses with pink lenses, which are also from Mango.
