Anonymous1: Weird how this is inappropriate in ways you won't think.
In real life, there are places where women can walk in public topless, but it usually comes with the law saying they can't grope their breasts.
Undertale has several humanoid monsters that don't wear clothes like the yellow and brown striped monster Undyne is friends with, the "So Sorry" monster, and Aaron, meaning they likely have the same type of laws as the real world's topless laws.
So, realistically the illegal part isn't her being nude in public, but she is using her hands to cover herself.
