Plumber's set

The Plumber's clothes is a set of vanity items made up of the Plumber's Hat, the Plumber's Shirt, and the Plumber's Pants. The color is red on the PC version and blue on the console version. The Plumber's Hat is very rarely dropped by Fire Imps, at only a 1 in 500 (0.2%) drop rate. The shirt and pants can be purchased from the Clothier for each during a full moon.

These items are equipped in the Social slots as they do not provide anything but a change in visual appearance of the character. If you have Rocket Boots equipped as well as the Plumber's hat, the animation for the boots while in use will change from purple to red sparks.

Trivia

 * This set of vanity clothes is a reference to one of the most well-known video game characters, Mario
 * The fact that you can only purchase the Plumber gear on the night of a full moon is likely due to the old stereotype of the "Plumber's Crack"
 * The blue on the second type of the set is likely a reference of Mario's original costume which was originally designed as blue and red, but then changed to red and blue
