CUP OF CHARLOTTE: Charlotte Ronson has a new pick-me-up: She’s designed a limited-edition ceramic tumbler exclusively for Starbucks. The tumbler, which depicts a sketch of a woman falling asleep on a bed of daisies in the sunshine, will retail for $14.95. It will be available at starbucksstore.com, starting Tuesday, and at participating Starbucks in the U.S. and Canada beginning June 25. “While designing, I was thinking of lazy summers and just enjoying the sunshine. There is something so beautiful and whimsical about falling asleep on a bed of daisies. I incorporated one of my signature floral prints, and a sketch was created to capture the moment. I’m so excited to use my cup this summer,” said Ronson.
