What is the ruling on using perfume to remove the smell of sweat when there are men who might smell the scent?

There is no objection to a woman with an unpleasant odor using perfume, incense, and other pleasant fragrances, provided that no non-mahram men smell them. If there are non-mahram men who might smell them, then it is forbidden for her to do so. In that case, it is sufficient for her to bathe, change her clothes, and avoid the causes of sweat. To treat unpleasant odor, it is advisable to consult medical professionals.
