Magical Girl Day.

All of the monsters and NPCs get frilly dresses to wear. The bunnies all wear Sailor Moon costumes. In Hardmode Hallow and Corruption/Crimson enemies drop Light/Dark Cloth respectively, which you can use to craft Cure Black or Cure White armor. It has little defense but increases your damage by a lot. It also lets you call down a beam of lightning every minute.

Special Magical Girl enemies spawn. These are cute little girls that do a lot of damage and have a lot of HP. They use the power of love to shoot lasers at you. They're extremely tough to defeat, but once you do, they usually drop a powerful weapon from a magical girl anime. They may also drop mascot characters from this sort of anime, which can fight by your side as summons.

Also, the Clothier sells costumes of various magical girls throughout anime.
