When : Always October 17th
Wear Something Gaudy Day is your chance to really stick out in a crowd.
The word ""gaudy"" refers to something bright, gay, cheap, showy, outlandish, or otherwise not in good taste.
Have a little fun on this day. For just one day, forego fashion and style. Look for something to wear that's really wild and wacky, and will stick out like a sore thumb wherever you go. If you don't have anything like this in your wardrobe, perhaps a friend does.
Note: If you're always garbed in gaudy attire, this is your day to look like everyone else!
