What is meant by the prohibition against a woman taking off her clothes outside her husband's home, and does this include the home of her family or relatives?

Summary of the answer:

The two hadiths narrated by Aisha and Abu Umamah, which state that "Any woman who takes off her clothes in other than her husband's house has torn the veil between her and Allah," or "Any woman who removes her clothes, Allah Almighty will tear off her veil," are intended to prevent a woman from being lax in uncovering her clothes outside her husband's house, which could lead to the exposure of her awrah (private parts) or her being accused of intending immorality. However, removing clothes in a safe place, such as the house of parents or maharim (unmarriageable kin), for a permissible purpose such as changing clothes or getting fresh air, is not blameworthy.
