Hugo Boss was at Happy Valley Racecourse recently to launch its Boss Black autumn collection with about 600 guests in attendance. Erecting a giant tent in the paddock area, the menswear label's aptly named Electro City event made use of the race track's giant screen technology to project a light show that pulsed to the beat of the music. The evening continued with a party and sounds provided by British singer-songwriter and DJ Calvin Harris. In attendance were Boss Black creative director Ingo Wilts and celebrities Michelle Yeoh Choo Kheng and Karen Mok Man-wai. Also present were South Korean actress Kim So-yeon, Andy On Chi-kit, ballerina Tan Yuanyuan, Stephanie Means and Lawrence Chow Chun-wai.
