We're always interested to see what Chanel are up to next so imagine our delight when we learnt they're the latest in a line of beauty brands to take on a pop-up store, a limited one-stop shop for all things beauty. Chanel's version opened in the heart of London's Covent Garden yesterday and is possibly the most glamorous temporary boutique we've ever seen. Housed on the corner of the Piazza it's the place to preview exclusive products whilst also feasting your eyes on the brand's huge collection of everything from nail polishes to iconic blushers and gorgeous palettes. As well as a nail bar in the basement (£20 for a shape and polish redeemable against purchase on the day), they've promised us they'll be announcing special make-up classes and interactive services that you lucky people can all take advantage of. The shop runs until December 2012 so there's plenty of time to get down there. Oh, and what's more, look out for the London taxis that have had a chic Chanel make-over, they'll be out and about for service from August.
