不注重打扮的英语

that 怎么与who一起用呢？应该用其一吧。I'm a persen who don't take great care of wear。wearing是形容词

needn't rigged out in your best.

Do not have to dress up

The old professor doesn't concern too much about his dress.

I am not a notice in person。其实你的也可以只是takes great care of改成pays attention to要好点。要是觉得满意，记得给我个满意。
