What They Tell Us:
Look, the entire point of a superhero costume is to look cool. Kick some criminal's ass in jeans and an undershirt and you're Dog the Bounty Hunter. Kick the same criminal's ass with a boomerang that matches your animal mask, and you're the goddamned Batman.
Ruby as Loki, the Norse godess of memorable superhero costumes.
Why It's Bullshit:
Making your own superhero costume is an enormous pain in the ass, and the difficulty level goes up proportionately to how flamboyant your alter ego is. To quote Ruby:
"I've gotten requests where a client wants exactly 10,000 rhinestones on a costume. Or where they want 50+ hours worth of beading work to be done in 36 hours."
Yes, that was a 50 in there. As in more work than most of you put into your job this week counting time spent trolling Facebook. Of course, when you're a real superhero, you're not designing your costume for a bunch of guys whose dicks have OCD. But if you're looking to maintain any sort of secret identity, you are going to be making it by hand just like Ruby--even Bruce Wayne had to put his own first suit together. So every hole in your costume is going to cost you hours at the sewing machine.
