وَلَبِسَ ثَوْبَيْنِ جَدِيدَيْنِ أَوْ غَسِيلَيْنِ إِزَارًا وَرِدَاءً
Translation: And he puts on two new or freshly washed cloths: an izār and a ridāʾ.
Izār is the lower wrap, and ridāʾ the upper wrap. Jadīdayn aw ghasīlayn shows that new cloth is not required: clean washed cloth also serves.
This describes the usual male pilgrim’s dress. Women are not required to adopt the same two-wrap outfit; the rules of their modest clothing are different.
