"I come from a family that embraces artistic expression," Charlotte Ronson said last night. The designer was the guest of honor at a fete for Nivea's new Kiss of Style cap contest, which encourages people to express their creativity by designing their own lip balm packaging. Ronson got in on the action, too, creating packaging inspired by the geometric designs of her Fall 2012 collection. Fancy yourself a designer, too? Starting Aug. 1, you can create your own cap using an extensive list of colors and design elements ranging from graffiti to Victoriana. Ronson will select the top 10 finalists, with the winning design appearing on shelves next year.
