Question…what do fashion designer Jenny Packham and beauty heavyweight Lancome have in common? Well both brands count the Duchess of Cambridge as a fan.

Kate has worn several of Packham’s designs and on her wedding day used Lancome’s Hypnose Mascara and Artliner. So it’s no wonder then that the two brands have joined forces to create the lust-have of the season.

The Jenny Packham for Lancome make-up bag is inspired by the designer’s spring/summer 13 collection, which featured plenty of polka dot prints. And it seems like the Duchess has been taking note of the trend, having been spotted in a monochrome Topshop design.

The limited edition make-up bag is available in pink or white, and comes filled with an array of travel-sized Lancome products.

All you have to do to get your hands on this complimentary arm candy is to buy two or more Lancome products (one must be skincare). The offer is exclusive to Harvey Nichols from now and runs nationwide from 1st June.
