If you're a millennial and addicted to online window shopping, you've definitely happened across Nasty Gal [1]. Founded by Sophia Amoruso in 2006, the site has become the must-click shopping destination for girls with fun, funky style. It makes total sense, then, that the label has partnered with MAC Cosmetics (the go-to beauty brand for cool girls everywhere) for a highly curated and chic collection. "MAC and Nasty Gal are both young, colorful brands that complement one another," Amoruso told WWD [2]. And trust us, the collaboration's hues (reds and purple) will definitely complement your Nasty Gal outfits. The best part? Since the collection consists of three lipsticks and a nail polish, you'll have no guilt buying the whole thing — with plenty left over for your holiday dress budget. Get a sneak peek now before you shop online and in stores Dec. 4.
