I much prefer the full chain shirt look for Red Sonja...



or the leather armor for her...



than I do the traditional chain mail bikini.

I also prefer the armored look for Conan (which was much more common in the Howard stuff except in the early years of Conan's life)...



to the fur briefs he wore through much of his Marvel years, but even sticking to Marvel, I preferred the simple kilt-style loincloth to the fur bikini bottom he wore

I also love Darwyn Cooke's alternate Wonder Woman costume from New Frontier more than any of her other looks...



I also really dug the Sword of the Atom era look for Ray Palmer more than the traditional Atom costume...



I also really like the GL costume for JonStewart (as seen in the JL animated) with more black through the torso area...



as for some of the others mentioned previously in the thread, I always like the blue swirl Aquaman look, loved the gypsy Scarlet Witch design, and dug the Tim Drake era Robin costume, but as for Iron Man, I never liked the red and silver centurion armor-it seemed a step backwards in bulkiness-tech gets smaller and leaner as it gets better, not bigger and bulkier, it happened in the switch from the gold to the red and gold and it happens in just about every other type of tech, but the red and silver just seemed clunky, less streamlined and more a regression than an improvement to me. It always took me out of the story wondering why Tony would make a backwards step like that trying to showcase his genius in bettering tech at the time in the books as he built a new company.

I, too, like the brown Wolvie suit.  Though the yellow suit looks nice, the brown suit is more appropriate for someone named Wolverine.

However, I hate, hate, HATE the Storm mohawk.  The leather biker outfit there doesn't help.  Perhaps the beginning of the end for the X-Men for me. Well, not really, but close to it.

Yeah, that Black Knight costume is pretty nice.

Ugh, I hated that one, though mostly the coloring.  It made no sense not to be red, white and blue.  Steve Rogers was not going to give up the stars and stripes for any government flunkie, no matter what they said.  Nomad had taught him it was more than just a costume, it was a symbol that meant something.  Steve Rogers would continue on, whether he could call himself Captain America or not.

I did like the alternate take on the Cap costume, though, used by The Silver Ghost, in the Freedom Fighters, when they did the unofficial "crossover" with the Invaders and Silver Ghost masquerades as Americommando...



Where Cap's was blue, his is red; where he Cap has vertical stripes, his are horizontal; where Cap had the single star, he has the ring of 13.  The round buckler shield became a triangular Templar shield, with concentric circle stripes becoming horizontal stripes.

I liked the Zatanna superhero costume (way more than the elf costume she had when she joined the JLA); but, speaking as a leg man, the original is hard to beat!  I did hate the later redesigns of that, for things like 7 Soldiers; made her look like a stripper, rather than a stage magician.

I never read this series, but a blue water-themed costume made sense.

I'm sure I'm in the minority, but I thought Namor's black costume from the 70's was infinitely better than the green speedos.
