Is it permissible for a woman to remove her clothes to try on others in commercial stores, knowing that she does not completely undress, but rather wears the new garment over light and modest clothing?

It is forbidden for a woman to remove her clothes outside her husband's home, except for revealing her modesty between herself and her Lord. This includes changing rooms in commercial stores, which may contain hidden cameras or two-way mirrors. Therefore, a Muslim woman must protect herself by not removing her clothes in such places. She can estimate sizes by bringing a piece of her own clothing or by arranging with the seller to take the clothes home to verify the size.
