Club 21 has launched a mobile application for iPhone and Android users. This means that you have access to the latest news and arrivals from more than 200 boutiques (including Lanvin, Comme des Garcons, Dries Van Notel and many more) wherever you are with just a couple of clicks and slides. Plus you'll receive regular exclusive updates and promo deals.

For non-members, simply sign up at http:www.club21global.com/mobileapp and the online team will track your spending at the boutiques (minimum spend: $800 before you're allowed access to the information).
