Working from home has made me dead set against wearing uncomfortable clothes ever again. If they're clean and not wildly silly looking what does it matter? Anyone that stresses how anyone else dresses after highschool seriously needs to take a long hard look at their life and fix themselves/mind their own business. You'll pry crocs, tshirts, and sweatpants out of my cold dead hands.
Also, if people complain that crocs make their feet smell they're telling on themselves and their poor hygiene. Their unwashed stanky fungus feet have just been masked by absorbent socks or unchallenged by totally open flipflops. Wash your feet you nasties.
Are you in highschool? Why on earth do you care what shoes other people put on their feet?
