devils advocate
but...you are doomed if you have a specific icon in mind...or if you want an asymetrical uniform or if you would like collared tee's or any number of other things. while the character creator is robust (extremely so..and I love it to death) I still bump into that wall that prevents me from creating the characters as I envision them...and they aint really all that off the wall if you ask me...heck my characters are down right tame compaired to most of the folks out there.~
...the sword is truth...

oh, I believe you Whiteperegrine! I prefer the more simplistic costume design. I guess that is mostly because I'm 42 and slightly conservative.
Good points, all. I have also experienced that special frustration that occurs when you can't get a costume that matches the picture in your head. I've tried several costumes meant to evoke a christmas tree, and have only been marginally successful.
That being said, my greatest frustration is also with the chest icons. The chest icon is a fundamental part of many (most?) super-heroes, and it's aggravating not to be able to upload our own.
Of course, that limitation also protects us from a world full of "Picture of a ******** Man" and "Phallic Symbol Guy".
And ho' man... and... uh, yeah. 
SusieBot, I could not help but to laugh! Maybe limitations is a good idea. I mean, c'mon, Assperaguts-man? Super Carrot-Top? Depressive Goth-girl? Bad Ideas!
This is an example of an unusual design.

He is no match for my Robosaurus!

I've heard several people complain about certain limitations in the costume designer when they are working with a limitating character. A good example is a Dragon character.
I agree that a dragon can be very limiting, but there are still things that can be done to make the character unique. Sure you start with the base of a monsterous lizard head, hands and legs and add reptile texture, But the colors and add-ons help from that point on. If you look at it, besides colors, you still have shoulder, chest and glove elements you can change. And if you really want to go wild, use robotic arms instead of tights.
Without the robot arms, I counted at least 10 shoulder elements that I though looked good for a classical dragon. I counted 4 chest elements not counting the logos and letters that looked good. And over half of the glove features worked well.
But the point is, don't be afraid to work with a charater that you think might limit you and your creative ideas. Just try it out and you might be surprised. I know I was when I put wrapped gloves that were on monsterous hands. That look blew me away on a dragon. Now DragonKnight ranks up there with the rest of my toons as toons I think are cool. (but that's just my opinion)(The opinions express in this post do not reflect the opinions of the forum or their parent companies or their subsidies.)
