Is the Ifadah circumambulation valid if a woman wore transparent socks out of ignorance? And what should she do if it is not valid?

For the tawaf (definition) to be valid, covering the 'awrah is a prerequisite. For women, this constitutes the entire body except for the face and hands, according to the majority of scholars. However, Abu Hanifa does not stipulate covering the 'awrah for tawaf.

If the socks cover the color of the skin, then the tawaf is valid. If a part of the 'awrah becomes uncovered without negligence and is immediately covered, the tawaf is not invalidated.

Furthermore, a woman discovering after the tawaf that her socks were slightly transparent does not affect its validity, because a covering that is slightly transparent upon close inspection validates the prayer, albeit with some reprehensibility. The tawaf is similar to prayer in requiring the covering of the 'awrah, in addition to the permissibility of acting upon a less preferred opinion (such as the Hanafi school's view on not stipulating 'awrah covering) after the event has occurred and rectification is difficult.
