Clover isn’t really affected by extreme temperatures and has no clothing preferences other than keeping their knees exposed (so they don’t destroy their pants when the monster legs come out). the majority of their wardrobe was picked out by Akemi, who basically treats them like a dress-up doll.
pondering a few variations on a theme… this character only appears in dream sequences and flashbacks, so her appearance differs a bit based on others’ perceptions.
don’t worry about the one on the right. everything is fine.
