Our favorite news today is that Charlotte Ronson is collaborating with Estee Lauder on a makeup line. The downtown designer will release a limited-edition set of colors in her name later this year, which will be available at the Charlotte Ronson store (and hopefully a few other places, for those of you who don't live in Soho). We've always had dreams of a Charlotte Ronson Lipsmacker, but this seems just as good. We can't wait to see the colors, but we imagine they'll be half pastel and half neon, just like most of Charlotte's clothes. If you're as obsessed with the Ronson collection as we are, check back tomorrow, when we interview Charlotte for the latest installment of Inside the Designer's Studio. We promise it will be really pretty.
