I have never been much of a make-up wearer. I love it, but it never seems to work for me. That is until I discovered the Chanel blush 'Fresque'. Honestly, it is the best, most natural looking blush ever. It gives you a slight glow without being overpowering or unnatural.
This is a screencap I took from a DVD that came with Vogue Paris a while back. It is taken from a scene where Peter Philips is teaching the other make-up artists the look for a Chanel Couture show, and he uses Fresque.
What are your beauty holy grails?
