What to wear on mismatch day?

Hey there, I'm curious, have you ever participated in a mismatch day? If so, how do you go about deciding what to wear? Is it a free-for-all where anything goes, or do you try to find some semblance of style amidst the chaos? Do you aim for a comical mismatch, or do you strive for a subtle yet eye-catching one? I'm genuinely intrigued to know how people approach this concept and how they pull it off. What are your thoughts on the matter?
