Peach's costume from Mystery Land from Mario Party 2, recreated to fit Smash 4's art style! The MP2 costumes were obvious choices for Smash alts, I'm surprised they never got included in the base game.
I replaced Peach's three f-smash tools with props from different Mario Party minigames. Her golf club is replaced with the "A" flag from "Shy Guy Says" (Mario Party 1 & 2), the tennis racket with a giant crayon from "Etch 'n' Catch" (Mario Party 3)/"Trace Race" (Mario Party 4), and the frying pan with the hammer from "Bowser Bop" (Mario Party 4). And instead of using her hat for her f-air attack, she uses the Skeleton Key item from Mario Party 2 (big thanks to GrimNaga for creating the model)
For version 2.0, I've overhauled a majority of the costume. The hat, belt, collar, and boots are imported from Super Mario Odyssey's Explorer Peach costume. The sleeve bows and pocket are now fully-modeled. The textures have been re-worked and the Skeleton Key has new metallic mats. A new render has been made from scratch.
This costume comes with a metal model and all of the necessary UI, and is texID fixed to go over any slot. The texID values are in the README included in the download.
