Alternate universe stories are a staple of funnybooks. Things like
Elseworlds and Imaginary Stories are used to show takes on the characters that aren't the norm. Sometimes in-continuity stories will have the characters visit a neighboring world where things didn't turn as they did on their own world. Sometimes they're fun, sometimes they suck. But what's cool about most all of them is that they have to take something familiar, make it something new, but still keep it recognizable. Even when the stories suck, I'm often impressed with the design work. So here we have 10 Superman costumes from alternate universes, each more darling than the last.

Just to be nice, we're gonna start off with a good one, Justice Lords Superman. Justice Lords Superman comes from a universe where Superman, fed up with Luthor, finally crosses the line and kills him, his first step towards leading the Justice League into turning the world into a police state. The regular Justice League eventually whoop them down. Man that was a good show. You know why this one works? Because it's simple, and black and white almost always looks cool. And you know it's Superman.

Superman as a Union soldier during the US Civil War. It's okay, I think the "USA" in the shield is clunky and can't help but feel whoever designed really thought they were being clever. The story it's from is pretty dry and has a mild twist towards the end that's supposed to make you think but just seems hacky.

The premise of True Brit was "Wouldn't it be funny if Superman landed in England instead of America?!" The reality of True Brit is "Haha, Superman's drinking tea and his parents are uptight!" John Cleese co-wrote it, they say. He's better than this. The costume's not bad. It's meant to be funny to some degree, but I think it'd only take minor tweaking to make it work as a more straight take on the idea.

Red Son, one of the most popular Superman stories of the last 20 years. I don't like a lot of Millar's work, but he got a lot right in this. Superman's a hero, in the US or the USSR. There were a few artists on this mini, so I don't know who designed this, but it's great. It says Superman and USSR, which is exactly what it should, and it does it simply and effectively. Doesn't hurt that that's a great drawing.

DC can make some very, very poor choices.

"
Superman's Metropolis is a DC Comics comic book Elseworlds publication and the first part in a trilogy based on German Expressionism cinema."
It's every bit as pretentious as it sounds. Funny thing about that book, the design work is beautiful and the art is great, they just really, really dropped the ball on Superman himself.

Superman lands on Apokolips and is raised to be a soldier of Darkseid. He wore that armor. It's alright, but you can't see Superman in it, I think.

Superman lands next to the Waynes instead of the Kents, ends up becoming Batman. I like the Batman costume. The Superman one, not so much. And by not so much, i mean not at all. The words 'painfully 90s' come to mind.

One of the most popular Elseworlds ever. An older Superman comes out of retirement after a tragedy to help make the world better again. The costumes only tweaked, no shield on the cape, muted color, black belt and a new version of the shield, but I love this design. It's simple but really fits the world of the story it was in.

Justice Lords was a better take on the Fascist Superman concept, but Brave New Metropolis got there first. Lois is killed, and in his grief Superman cracks down on crime to the point of declaring martial law where he is the dictator and the army. The only thing about this that says Superman is the modified shield and spitcurl, but that's all it seems to need. I think this one is really effective.

This one comes from a universe where Dan Jurgens commits hate crimes against comics and is not punished for it. Sadly, that universe is ours.
