Interesting attire for sleeping on a cloud: crop top, short skirt, and a pair of knee-high socks. She'd freeze with her tummy and thighs exposed like that! Aesthetically, though, it's fantastic, and its cute.
While most people don't think she'd ever wear something like this being a tomboy, that's exactly why I think she would wear something like this, at least to bed. It's like saying "Who the hell cares who sees? It's late don't bug me." And yes she would have a roof if you've ever seen her house... made of CLOUD! OoO
