Ooo, YSL mystery glammer! Sounds awesome. I have only tried one YSL product, and that's the Touche Eclat highligher/concealer. YSL lipsticks have always been a fantasy product of mine.
I'd love to try this one! http://www.amazon.com/Yves-Saint-Laurent-Volupte-Lipstick/dp/B003B2SB3C/ref=sr_1_7?s=beauty&ie=UTF8&qid=1418156595&sr=1-7&keywords=yves+saint+laurent
Thanks, YSL mystery glammer!
