How to Muslim
Islam gives men and women a dress code, and it is more specific than "cover up". This page sets out what actually has to be covered, what the clothing itself has to do, and where the rules come from.
O Prophet, tell your wives and your daughters and the women of the believers to bring down over themselves [part] of their outer garments. That is more suitable that they will be known and not be abused. And ever is Allah Forgiving and Merciful.
Haya' is usually translated as modesty, though it sits closer to a sense of shame that keeps you from doing something unbecoming. It shows up in four places:
The Prophet (peace be upon him) tied modesty directly to belief rather than treating it as a matter of culture or taste:
The command to lower the gaze comes before the command about clothing, and the men are told before the women. That order is deliberate.
The clause about drawing the headcovers over the chest is the verse most directly behind the headscarf.
A man's awrah, the part that must stay covered in front of others, runs from the navel to the knee. This is the minimum, not the target, and it holds in front of other men as well as women.
Letting a garment trail below the ankles is specifically warned against for men. The point is what it signalled: wealth shown off by dragging fabric in the dust.
Covering skin is not enough on its own. Cloth thin enough to see through, or cut tight enough to trace what is underneath, has not covered anything. Clothing worn to show off wealth or status fails on a different count.
Men do not wear pure silk or gold jewellery. Both are permitted to women. A silver ring is fine, and so are blended fabrics that are not predominantly silk.
Men do not wear what is distinctly women's clothing, and women do not wear what is distinctly men's. What counts as distinct varies between cultures, which is part of the ruling rather than a loophole in it.
In front of men outside the family, a woman covers her body. The hair, neck and chest are not an open question: covering them is obligatory, and that is what the headscarf is there for. The same goes for the arms and legs.
In front of other women, and in front of mahrams such as a father, brother or son, the rule is far lighter and ordinary clothing is fine.
Praying alone, a woman covers everything except the face and hands, and a headcover is required even at home.
Length alone does not settle it. A garment has to actually perform the covering:
Clothing is the outer shell. The rest of haya' is harder and matters more:
The Quran names clothing as a gift, then immediately points past it:
Nothing here asks you to look shabby. The same chapter that sets the rules tells people to dress well for the mosque, and the Prophet (peace be upon him) owned a cloak he kept for delegations and Eid.
This page takes one position and sends the contested part to a local imam. For a different view, argued at length:
