"Mario’s Closet" by Glen Brogan. I hope he picks Kuribo’s shoe! Before you point out any outfits missing from the plumber’s wardrobe, refer to this note from Brogan:
"I wanted to include as many of his power-ups as possible, but the main rule I had to follow was that I couldn’t include things that actually transform Mario himself rather that just changing his wardrobe, like the Boo mushroom from Mario Galaxy that turns him into a ghost. So I’ve mentally prepared myself for the barrage of ‘OMG WHY DIDNT U INCLUDE THIS 1 ON THERE U R DUM.’”
The design is currently in the running for a possible t-shirt at Splitreason, so vote for it if you’d wear this!
