What is the ruling on a woman wearing short clothing in front of her mahrams?

Question:
What is the ruling on wearing a short garment in front of mahrams, and wearing short sleeves?

Answer:
A woman should cover her body and beware of being lax. She should not reveal to a mahram anything other than what is customary, such as the face, the hands, and the feet. This is the safest and best for her.
The scholars have differed on what she is permitted to reveal to a mahram. Many scholars hold that she reveals to him the face and the hands, some mentioned the feet, and some mentioned the head.
Therefore, the conclusion is that she should be cautious and limit herself to the face, the hands, and the feet. If there is a need for part of the head to be visible, there is no harm in front of a mahram, such as her brother or her uncle. However, being cautious in this era is more appropriate. Being cautious around some mahrams is more appropriate because some mahrams have no religion or very little religion. She should be cautious in this matter when she is alone with him, and she should be extremely covered regarding anything that might lead to temptation. The face and the hands are sufficient in his presence, especially if he is not to be trusted.
