I wear a shirt shalwar so as my wife. However the difference is there as you know about Indians and Pakistanis.
Answer
It is prohibited for a woman to don such garments which are specifically
designed for males. However, if it is not a special dress for men, but
rather worn by both males and females, it will be permissible. (Fataawa
Mahmoodiya vol.5 pg.219; Maktaba Mahmoodiyyah)
It is also prohibited for a female to wear a tight fitting garment that
reveals the form and shape of her body.
