Uniform Stealing Board

Found thanks to the Mugged for Disguise page of TV Tropes. Features the classic 'grabbed from offscreen to be knocked out'. In Chapter 49 the titular Demon Queen disguises herself in the clothing of an unfortunate adventurer who got grabbed and knocked out by one of her demon generals. The general in question later admits that she was so focused on finding a victim with the right clothing that she didn't take into account that the disguise wouldn't hide Velverosa's horns or tail... The unconscious adventurer is briefly shown, but the demons were actually kind enough to cover her with clothes to protect her modesty. (One of them even mentions it!)

Here is the link. The scene starts at the beginning of the comic strip.

very enjoyable

But these demonettes are confused to say the less. In their line of work Demonettes aren't interested to protect the modesty of their victims, quite the opposite
