Does not even scratch the surface!
nd that's just recently saved pics! My favorite "serious"-but-ridiculous Supersuit was the varieties of black (which look good, I loved the scene with Zod and Kal in black suits in Man of Steel) by Byrne that had the soap bubbles along the arms. The nobody-shows-skin-on-Krypton period.
Sometimes overblown art can be funny or get a point across, but mostly it's just too unrealistic. One example was Rags Morales working so hard on Brad Meltzer's Identity Crisis to make the JLA individuals, like Sue Dibny based on Dawn Wells and then had to draw Superman as oversized with absurd musculature. Where can Superman ever have a decent work-out? Those muscles don't just grow, not in humans, and most Kryptonians we've ever seen seem quite within normal limits. Christopher Reeve was the biggest Superman, 6' 4" and 220 or so. Cavill has the perfect Superman anatomy as far as I'm concerned. Totally straight and without any vestige of gaydar whatsoever, that is still a gorgeous man. He looks like I wish I looked. Great, powerful hands, too! (That's important.) Kirk Alyn was likely the smallest, which means nothing. He was terrific, and had an attitude as Superman that just made you smile. Dean Cain is right around Alyn's size, albeit with much more modern methods of exercise and body-shaping from his football quarterback (or whatever he played) days. Tom Welling is 6' 3" and pretty cut, pity he was in The Suit for only one shot. George Reeves was probably the most "normal-guy" physique on the muscular side. Totally fit for the 1950's type of strong-man (not as in circus, more as in works hard on the farm every day, which fits).
Variant costumes are frequent. I think Waid and Hitchy used them as a trophe in their JLA run. Black Canary even said mind control or turning to evil usually meant a change of costume!
