While September weather continues to play havoc with your style and patience, let's take a moment to thank Alexa Chung for giving us hope via her New York Fashion Week white-minidress triumph. A lesson in trans-seasonal dressing, she pairs her long-sleeved (v important to balance bare legs) Noon By Noor shift with adidas Superstar trainers. Note: white is a great move for when the sky is still too bright to dive into head-to-toe autumn colours. Snaps for the mini Anya Hindmarch bag, too, which gives all kinds of AW15 kudos.
