If someone promised you a candy bar and you later came to find out it was calorie free, you'd be bummed, no? We'd be livid, too. But, thanks to one of our fave designers (and sunglass-crafter extraordinaire), Karen Walker, we've got one cool candy bar that delivers more than you'd expect, while still leaving the calories behind.See, after selling out collections worldwide, Ms. Walker is taking her eye-wares on the road for a twelve-month-long journey around the world. Her traveling "Candy Bar" will pop up in retail stores, allowing shoppers to treat themselves to five new limited-edition candy-colored frames. So far, the only U.S. events involve a stop at L.A.'s TenOverSix from this Friday, May 25 through June 22 and at NYC's Cloak & Dagger from June 29 through July 13. That's a whole lot of time to get your, erm, fill, so we suggest you fully indulge.
