The Kassie by AG combines signature soft denim and vintage-inspired styling for a pair that works with every look in your wardrobe. In 2000, denim designer Adriano Goldschmied partnered with manufacturer Yul Ku to launch an innovative, premium denim collection. After serving as Creative Director for four years, Goldschmied left the company in the very capable hands of his partner, who has kept the business in his family for nearly two decades. Now led by Ku’s son, Samuel, AG continues to create chic, classic staples with sophisticated sensibilities. Each premium pair is responsibly manufactured and designed in Los Angeles, and fits seamlessly into your modern wardrobe.
