Over the past four years, Lee-jung Kim has made more than 1,000 brightly coloured hats which she wears while she goes about her daily routine in New York City. Lee says her first creation was a crown she made for a friend as a birthday gift. It inspired the 47-year-old mother to keep making butterfly-shaped headgear for a long-term project that has helped her connect with her daughter and other New Yorkers.
