I think of the "clothing" on most pokemon as the way Sylveon's ribbon-things are occasionally described as: sort of like feeling appendages that are actually part of their body. Imagine being pimp-slapped by the ones trailing off of Mega Medicham's arms/back/wherever.
Also, picture Slowking as a mutated Dilophosaurus from Jurassic Park. Same skin/appendage idea.

Well I think Mega Medicham's extra "arms" is just spiritual/psychic energy. It's more on the list because of the "turban" and "beads" around its "pants".
Got a point about the Dilophosaurus, though still doen't take away it looks like a frill being its two colors not part of Slowking's normal color scheme. :P
