Dubbed the "catwalk's best-kept secret", Wendy is one of the industry's foremost authorities on all things make-up and beauty.
She's a creative consultant for Burberry Beauty with Christopher Bailey and last year launched her own blog, where she shares product tips, reviews and beauty news.
Wendy's job takes her all over the world, although she mainly splits her time between London and New York.
She has worked on many high-profile photo shoots with top models including Doutzen Kroes, Lindsey Wixson and Gisele Bündchen and celebrities such as Kate Hudson and Nicole Kidman.
One of her most memorable shoots was with the singer Ke$ha, when she painted her whole face with an American flag for the front cover of V magazine.
