It wasn't Alexa Chung walking for Vivienne Westwood or the Pac-Man helmets at Giles that really caught our eye this London Fashion Week - it was the huge selection of quirky sunglasses featured at many of the shows. From the neon shades at House of Holland to the geeky reading glasses at Charles Anastase we loved them all and were determined to find out WTB (that's where to buy in Grazia shorthand). It shouldn't have surprised us that the genius behind the creations - which have been adopted by London's young fashion crowd Alexa Chung, Pixie Geldof et al - is Linda Farrow. And you'll be able to buy them - and glasses designed in conjunction with Preen and Luella too - from October. We don't know the exact date yet but you'll hear it hear first and until then start studying the pairs below to decide which are at the top of your lust-have list.
