Butterflies are usually associated with femininity, but also have connotations of resurrection, celebration and the soul. Aside from that, they vary in colour and patterns, making lovely inspiration for the fashion industry. Heres a bit of trivia for you; research on butterflies also led to the design of the wide wing kite and aircraft design.
Have you ever wanted to touch a butterfly? I haven't, they give me the heebyjeebys. But you wont hurt it if you do decide to touch one, but you may rub off a bit of its colour, which are tiny scales. A butterfly's skeleton is also on the outside of its body, making the butterfly related to crabs and lobsters! Butterflies are brightly coloured on top to attract a mate, and the colour underneath the wings are for camouflage purposes. Eeee its like watching QI, you learn all sorts!
Influences from butterflies have made their way into the fashion industry via structure and print. In 2008, they also fluttered into the Paris Dior Homme Flagship store. "Nine thousand black decoupage replicas serpentine across the ceiling and walls of the white boutique, like Hitchcock's birds only less menacing, and much prettier." The installation was there for a month.
