On October 15th, singer Lee Hyori held a fan signing for her endorsement brand 'Clio' at the Watsons chain store in Daehyun-dong. Although it was her first public event in a while, Lee Hyori was all cool confidence as she stepped onto the dais in all black. Her fish-scale top and sexy kill heels gave off a fierce charm, but her warm smile tempered the edge of her outfit. Interestingly enough, her�waterproof pencil gel liner (which was launched earlier last month) has already seen 100,000 units in sales, with most of the colors completely sold out. Seems like 'Lee Hyori effect' is still going strong! Check photos from the event below. [gallery link="file" order="DESC"] Source + Photos: Dispatch via Nate
