I think some of it is the "seeing the seams" problem. I'd hate to say "because realism" but, let's just take Daredevil here. Just one part of his costume.

Now seriously, how would you, as a costume maker, get a boot like the one on the right in the first place? The closest thing we have to them nowadays is cowboy boots - which you don't want to run around a city doing acrobatics in believe me. Plus they will not "hug" the leg like that or be skin tight. (they usually have handles on them to make it so you can pull them up) So well... the closest things you're going to get to the boot, is a lace up like on the right. (or maybe a kind with a zipper in the back? in either case I doubt the zipper is drawn in the comic)
Remember the most comic-book accurate costume we got of Batman was from Adam West's TV show. And you can watch several other superhero serials from back in the day to see what it was like when they really tried to make the costumes accurate (since simple tights could be done a shoestring budget). Some things are just going to be a consequence of tweaking things for reality. i.e. If Spiderman were to have a one piece outfit that allows him to do a split with his legs, then there's going to be a bulge in the crotch area where the extra fabric is to allow it.
We can also start posting videos of cosplayers who will provide in detail what the problem with every page-perfect costume is.
I'm sure we'll then learn that there were all kinds of unseen benefits to having women do the job. Like the warmth, heartbeat, and surrounding sounds helped reduce the chance the kid develops autism or something.
Not to mention that if DC ever stops printing it, the rights revert back to Moore so they've kept it in the loop ever since.
Yes they had a whole line of them.
