I guess to me it depends on what LW means by unwashed, unbrushed, dirty, and mismatched. If she's wearing an adult man's shirt, too-small pajama pants that smell, unmatched shoes, has rat's nests in her hair and stinks, that's a huge problem. If she's wearing a t-shirt and pants and sneakers that aren't color-coordinated and was slightly dusty with an off-center ponytail because she'd just been to the park, not so much. Since LW says it's something that could be written off as her being 7, I lean more toward that end of the scale, though.
