“We’re going to a shoe party,” sang my three-year old daughter most of the way to Sunbeam Studios in wild West London on Saturday morning. While new product launches and shoe parties are a fairly regular occurrence in my diary, I don’t often get to take my daughter. But this was the launch of Charlotte Olympia’s Incy collaboration with Crayola - and it was exactly what little girls (and mummy’s) dreams are made of.
