I've been having fun with the New Leaf clothing designs
Here's the Skyward Sword Zelda dress. I know the triforce design is a little weird on the back part, but you can hardly see it in-game anyway, so I left it as is.
I've also designed a Midna dress (obviously won't look like Midna because you can't design pants, so I made it more "Midna-inspired"), a Medli dress, and a few Pokemon shirts. I figure those are plain enough that I'll only post them here on request.
