Halloween was created for the geeks, as it gives a legitimate reason for cosplay and is a perfect opportunity for sci-fi costumes. This list highlights the best and worst costumes I've seen so far and ultimately gives some serious Halloween costume inspiration.
From sexy Star Wars get-ups to steampunk superheroes, I hope this list of sci-fi costumes inspires you to geek it up this Halloween.
Implications - One of the best ways a company can interact with its consumers is by creating a submission contest or series that asks fans to send in pictures of themselves enjoying a company's product. By featuring fans on their Website or in press, companies engender goodwill as a brand who cares about its fans.
