We loved Alexa's effortless, assymetric updo at last night's Louis Vuitton Maison opening on Bond Street, so we called up Ms Chung's hairdresser George Northwood to find out how you can get the look at home. Tongs at the ready…

"Ok, firstly apply Kerastase Volumeactive Mousse, £14.60, to roots, mid lengths and ends. Then rough dry, scrunching all the time to give lots of texture. Next, part your hair to one side on a deep diagonal back to the crown.

To create the curl, use Daniel Hersheson waving tongs, £85 and tong the top few sections of the hair all the same way. To give it that effortless style make sure you rough up the hair and backcomb the roots, particularly at the crown. Pull into a loose pony and secure in place with a clip of your choice. Finish with hair spray and manipulate your hair so it sits exactly how you want".

Voila. Now all we need is her wardrobe...
