I have been noticing these lately in form of pins and patches. The "Pow!" and "Kaboom!" mixed with what I now call the Bowie fever. It also can be seen on Chiara Ferragni's coming up collection with the knee high boots with stars and many others.
The things to look for mainly, is the shiny fabrics, patch work, primary colours (red, yellow blue) and outlined designs.
Style it with strong shoulder jacket, and metallic heels for a power heroine look. Or keep it casual in the shades of blue to make it look more comic.
