Karl Lagerfeld lost a diamond-encrusted brooch worth thousands of dollars at the CFDA/Vogue Fashion Fund Award event Monday night. The Chanel fashion icon was mortified when it dropped off his tie during the bash at Skylight Studios. But BFA photographer Neil Rasmus found it on the floor, and rescued it. Rasmus told us, “I looked down and saw this 4-inch-long brooch covered in diamonds. I immediately gave it to security. Moments later, I saw Karl looking for it. He asked to personally thank me, and said, ‘Not many people would be so honest.’ Anna Wintour also thanked me.”
