For a superheroine, packing must be easy; their outfits are so skimpy there's barely enough fabric to fit into a purse. You could argue that male superheroes also wear costumes that leave little to the imagination, at least in terms of tightness, but it is female superheroes in particular that are depicted in practically stripper-esque outfits.
Fans have noticed, of course. On comic book forums you'll find comments like the following:
For one month I think DC should switch the male/female costume designs in all their titles. Wonder Woman would put on battle armor or something that shows no skin below the neck and Superman will put on knee high boots and skin tight biker shorts.
Others find the skimpy costumes irritating for practical reasons, in true comic book geek style:
...Huntress's "sexy" uniform makes me nuts. She doesn't have superpowers and there are important organs in your abdomen. Somebody cuts or shoots her abdominal aorta and it's all over.
In any case, artist Michael Lee Lunsford has started populating a Tumblr with his illustrations of, well, reasonably-dressed superheroines. Some of them are even wearing proper pants.
Lunford points out that he has no agenda, and is just doing the sketches for fun:
Point of this: An exercise in character design, attempting to clothe the heroines nearly all the way and not making them painted-on, while still keeping the look of their original costumes in some way. Hopefully keeping them looking as iconic as the originally were. Just showing what can be done with a costume breaking outside the barrier of the norm.
NOT the point of this: some moral code I'm trying to push on you.
What we'd like to see next: An industrial designer breaking down superhero gear, ID-Sketching style. Is Batman's utility belt made of injection-molded plastic with living hinges, or machine-sewn Cordura based on the MOLLE system?
