It will be published with the May issue of Harper’s Bazaar available from 1 April.
The supplement is aimed at the publication’s fashion and beauty-conscious readers and features images by some of the world’s famous fashion and beauty photographers as well as beauty tips from style experts and celebrities.
The Selfridges sponsorship deal includes a six page advertorial showcasing makeup looks and includes an invitation to an in-store event to celebrate the summer make-up styles.
The event on 20 May will be hosted by Harper’s Bazaar beauty director Newby Hands and Selfridges’ menswear and beauty director David Walker-Smith.
The deal is the first of several advertising led initiatives NatMag has planned for its luxury titles group, which includes Esquire and Harper’s Bazaar.
Luxury group publishing director Tess Macleod-Smith says: “This first supplement is one of several initiatives that Bazaar is launching in 2010 as part of its commitment to the beauty industry.”
