Fashion designer Diana Eng has created a beautiful retroflective scarf. She says:
I love the lightweight scarves everyone is wearing indoors, outdoors, and in many different configurations. So I decided to create my own with subtle stripes of tiny retroreflective lenses on the fabric. What normally appear as grey stripes, illuminates with reflected light when exposed to a direct light source. It makes people do a double take to check out what you are wearing.
