Would you believe we're already more than halfway into London Fashion Week? Sigh. Days are rolling past way too quickly for our liking. To recap, Day 4 began with a more sombre mood, with the tribute to Alexander McQueen bringing the international fashion pack together. There were also some amazing shows on display from the likes of Christopher Kane and Peter Pilotto who both delivered stand-out collections. Admittingly, there are a few celeb appearances we've missed this year (Kate Bosworth, where are YOU?), but the heavy dose of Olivia Palermo and Alexa Chung is doing its best to satisfy us all the same. Have a scroll through today's pick of celeb spotting and let us know who you think is missing from the front row!
