I had been seeing these Dion Lee reflective knits for a while but I didn't really know how they worked, however knew I wanted to try them for myself. It's so ingenious and I love that Dion always pushes the boundaries, its amazing to see. The fabric is a knit and when a flash goes off it picks up on the reflective material, and voila! Glow in the dark, reflective fun! So why aren't more of our clothes glow in the dark I hear you say? I'm not too sure, but boy is it fun!
