Actually, if you catch a monster girl in a dungeon and then go into their overview on the victory screen, you can go to your active girls and both remove equipment you don't want *and* put equipment that got shredded off back on.
So... is it just me or does the 1.0 release seem to be missing visuals for some of the monster girls currently? Namely the Cowgirl off the top of my head which I'm sure had visuals implemented prior to the full release.
