What is the religious ruling on a wife wearing revealing clothes at home while her husband is fasting, and she is sometimes fasting, and the wife is not convinced to cover her body despite the husband's request?

A husband is permitted to see his wife's entire body, provided that no one else sees her, as the Messenger of Allah, peace and blessings be upon him, said: "Guard your 'awrah except from your wife or what your right hand possesses." However, if seeing her arouses a man's desires and leads to breaking his fast by the emission of madhy (pre-seminal fluid) or maniy (seminal fluid), then he must distance himself from her or instruct her to cover herself.
