Thank you for reaching out to us.
It is permissible for a woman in
niddah to wear perfume as she ordinarily does, as long as she does not use extra perfume or a special scent in a more intimate setting with her husband.
A woman's husband can be in her company when she is wearing perfume, but he may not deliberately smell the perfume she wears
during niddah.
Please get back to us with any further questions.
