Musannaf Ibn Abi Shaybah

Hazrat Umm Atiyyah says that a woman whose husband has passed away will not use kohl or dye during her waiting period, nor will she wear colored clothes, but she may wear a cloth called 'asab. She will not use perfume, but while bathing after menstruation, she may apply a little of the perfumes called 'qist' and 'azfar'.
