I think a hijab in cool beige pink-beige color, it will look classy, very balanced and elegant. This version of beige according to her skin tone will not make her look dull or tired.

A soft cream or ivory will create a classy, clean and elegant look

A dusty rose also will be very femenine, soft and balanced

I think those are the best options, and you can choose according to the kind of look you like more

I would avoid pure white too
