Notes:

'A lot of people have been going the "OH NO BOO HOO POOR MII GUNNER" route when it comes to the Sans costume. I prefer to look at it from a different angle.

Also, I REALLY hope the belief that this is honest to god Sans doesn't make it an excuse to make literally everyone else in existence into a really convincing Mii costume. I can already see the Shantae Mii Brawler, Sora Mii Swordsman, and Master Chief Mii Gunner, among other things…' – OhhSeeDee
