The trend of wearing a skintight body suit complete with head-enveloping mask is a little strange to me ("Hey, it's a green faceless person in that college basketball crowd! Wow!"), but I suppose young people have to find new ways to have fun for me to find confusing. It's the way of the world.
Of course, some genius realized that these outfits need not be confined to simple monochromatic schemes and is rolling a line of Star Wars body suits, presumably for Halloween (or at least, I'd hope so). However, I will say, these costumes (available for Boba Fett, pictured above, Chewbacca, Darth Maul and Darth Vader) will probably show off a bit more lightsaber than is generally appropriate for most social situations.
