I see a lot of possible middle ground here. If LW thinks little girls should all be dressed up in cute matching frocks all the time, but Katie wears jeans with muddy knees because why wash jeans every day, or has a marinara stain on her favorite t-shirt because who doesn't, then LW might read that as "dirty mismatched outfits". It's really, really hard to tell from the evidence they've given us. Hair, too; is unbrushed hair "it's in the ponytail it's been in since this morning and it's started to come loose and I expect her to have a hair ribbon", or is it "full of tangles, looks like a rats nest."

(I admit I am also biased because who talks about a seven year old's mismatched outfits? I mean, shoes should be from the same pair, but if a seven year old wants to wear a yellow striped jumper and purple plaid skirt over jeans, that's a thing a grandparent laughs/groans about, not worries about. But if they say "yeah, grandpa, I wanted to wear this skirt with tights but momma couldn't find them and told me to wear jeans" that's what I'd worry about. And I can't tell which this is)
