4.1.26

nāyakasya vratam upavāsaṃ ca svayam api karaṇenānuvarteta/ vāritāyāṃ ca nāham atra nirbandhanīyeti tad vacaso nivartanam//

When the wife wants to approach her husband in private her dress should consist of many ornaments, various kinds of flowers, and a cloth decorated with different colors, and some sweet-smelling ointments or unguents. But her every-day dress should be composed of a thin, close-textured cloth, a few ornaments and flowers, and a little scent, not too much. She should also observe the fasts and vows of her husband, and when he tries to prevent her doing this, she should persuade him to let her do it.
