What is the agreed-upon limit among scholars, which, if exceeded by a woman in her attire, would make it reprehensible and necessitate condemnation? Is it permissible to attend events where immodest clothing is worn, and what is the ruling on a daughter attending such events?

The significant scholarly disagreement regarding the hijab (definition) of a Muslim woman concerns the obligation to cover the face and hands. Everything else is 'awrah (intimate parts) that must be covered by scholarly consensus. Tabarruj (display of adornment) is the act of showing off one's adornments and what provokes a man's desire. This includes thin clothing that reveals, tight clothing that shows the body's size, and soft, flowing clothing that describes it. The Sunnah (definition) described such a woman as "clothed yet naked." As for the clothing the questioner asked about (sleeveless, revealing the chest, short above the knee, with back openings, or very tight trousers with a blouse that doesn't cover the buttocks), it is unequivocally a reprehensible tabarruj. One should avoid attending such gatherings if changing the reprehensible act is not possible. There is no blame in the presence of a young, non-accountable daughter. Efforts should be made to rectify the situation by advising the husband's mother wisely regarding prohibited mixing and the clothing of those who display tabarruj.
