Well, I think that they're at least still wearing their uniforms in crystal tokyo, pretty sure they're depicted as doing so somewhere in the anime.
You'd think that if they _had_ integrated their forms they'd ditch the silly dress post-haste. Still, I've always liked the fan explanation that
the uniforms are the way they are for the express purpose of embarrassing the user so much that they try to integrate it's power as fast as humanely
possible. It's obviously not actually the case, but that particular answer amuses me to no end.
