It is narrated from Sayyidah Asma bint Abi Bakr (may Allah be pleased with her) that she went to visit her sister, Sayyidah Aishah (may Allah be pleased with her), while al-Zubayr (may Allah be pleased with him) was away from home. The Prophet (peace and blessings be upon him) came in and noticed the scent of perfume, and he (peace and blessings be upon him) said: "What harm is there for a woman in not wearing perfume while her husband is absent?"
