Yeah it's probably the muddy shading that makes the her look dirty, and it's also partly the artstyle. The cloth that the characters are wearing are all so wrinkled and "used" looking, it looks thin and has no form.
Her wardrobe makes sense as normal home clothes, and it's honestly something I would wear going to sleep, but it's way too thin to be worn outside. We've also only seen her wear outdoor clothes 2 times, and they're not that bad.
The artwork makes her seem really dirty. Maybe it's the overall tone of the coloring, but I just can't help but feel like she needs to constantly shower...and get a decent wardrobe. She dresses like lazy trailer trash. I just want her to wear a proper shirt and a damn bra
