Sephora has long offered a staggering range of beauty products, and starting this month, the French retailer is offering an advanced degree in how to use them: Sephora University Beauty Classes will be held every Sunday at select Sephora stores with a rotating curriculum including Smoky Eye 101, and the mechanics of skin care. (We’ve already asked them to add a tutorial on the golden eyelashes from the Dries Van Noten Spring 2014 show.) The W team recently attended a private class on cat eyes at the SoHo shop, where we learned how to wield the new Marc Jacobs Beauty Magic Marc’er Precision Pen. The key to a squiggle-free line, according to our teacher Hector Espinal? Just hold your breath. Wish we’d known that in college.
