So when I was getting dressed today, I very quickly put on a lab coat and some cat ears, not even trying to have something coherent, just wanting to have some kind of costume, and then I used some eyeliner to draw some whiskers on my face, so, yeah, that's my costume, cat in a lab coat, does it make sense? no. who cares. Still wearing the same skirt and striped knee-high socks from yesterday, but that's just my work clothes.
But then when I got to my office in the physics department, one of my colleagues was immediately like, "Oh! Schrödinger's catgirl!"
It both was and was not a coherent costume until someone observed you and collapsed the wavelength.
