Unlike most of the teenagers, my 13-year-old niece doesn't care about her appearance at all. She does what is necessary hygiene - shover, teeth brushing - but not a bit more.
She wears sweatpants and/or different really bright colors together, so she usually looks like a parrot. Yes, for school, too. She barely combs her hair, either, it looks like a giant birds nest.
I'm not saying that she shouldn't be wearing what she likes or force a given style on her, but I think that the root of the problem is that no one taught her how to dress appropriately. Her mother is ill, she can't even take care of herself, and her father struggles to keep the family afloat.
Additionally, my niece can't stand staying somewhere overnight without her parents, so I can't invite her over to "work on her". They also live 1.5 hours away from us, so it's not easy to hop in for a quick visit.
Her appearance is a big problem, as her classmates have ostracized her because she looks ridiculous, so she has no friends. It's a vicious cycle: the fewer friends she has, the less she cares, which, again, results in fewer friends.
Next year she'll start high school, and I think she needs some changes before that, because she has no social life whatsoever as of now, and I don't think that's healthy.
Can you give me some advice on how to achieve positive changes in her attitude to clothing and cosmetology?
