Don't forget The Hulk and The Sub-Mariner. Especially not The Sub-Mariner.
I like the outfits for Elektra and Red Sonja--they could be characters in a Dungeons & Dragons Fantasy HERO campaign. In fact, a lot of these outfits look like they belong in another genre besides a four-color superhero world. For some of the designs, that's a comment--for others, a complaint. It's like the artist kind of, sort of missed the point about super-character costumes--especially when it came to Vampirella.
Like any costume, a superhero costume does more than conceal the original identity--it creates a new identity, one different, distinct and immediately recognizable. Doctor Impossible says it best--
"In street clothes I'd just be a criminal. Which I am, of course, but in the costume I'm something more. I wear the flag of a country that never existed and the uniform of its glorious army, spreading forth the dominion of the invincible empire of me. Doctor Impossible."--Soon I Will Be Invincible, pgs. 89-90
Yes, you can fight crime without circus tights and a cape, or a high-tech battlesuit, or mystic robes. But a superhero's costume represents something more--strength and speed, power and prowess, and the courage to use all that for the greater good. And something more--the idea that others can do the same, can find it within themselves to use their strengths and abilities for truth and justice, for equality and liberty, for any other just and noble cause.
I don't quite get that sense from the costume redesigns on that page. Yes, they're practical, and yes, they're decidedly not "stripperrific." But I wouldn't call them inspiring--I wouldn't call them memorable.
Just my thoughts on the subject--take them as you will.
