I can't get enough of neon right now. Don't just limit yourself to a pair of neon jeans (Zara and JBrand have the best on offer). Neon can be enjoyed everywhere which may be good for some and horribly offensive for others.
I've already booked myself in for a pedicure to change my neon pink toes to yellow. Even though it's monsoon season in London at least I know there's a hidden surprise under my wooly socks.
