At Temperley, make-up artist Gucci Westman ensured the mix of Revlon's Matte Lipstick in Strawberry Suede and Really Red stayed put by layering Revlon's Just Bitten Lip Stain and Balm pen (which is out this summer) over the top to set the lipstick in place. Some of the models were hanging around for hours, eating and drinking, and the lippie didn't budge. I'll be trying this trick at home.
