Well, they definitely poof new clothes on when they change forms. "Ether" is basically a way to handwave the impossible stuff, starting with making sure the Titans don't collapse under their own weight and going down the list of plotholes from there. Blades probably solidify Ether and materialize a specific set of clothes the same way they make weapons. And if that's the case, then it may be possible to invent an Ether ray that dematerializes any Ether constructs made by Blades.





Such an invention would definitely have military applications, since it could be used to destroy a Blade's weapons and armor. And then, just as it was with the Internet, the porn industry would be the next to get their mitts on the same tech. From there, it would become public knowledge...meaning nudifier rays for everyone!
