Allah's Messenger (ﷺ) was asked what sort of clothes a Muhrim should wear. He replied, "He should not
wear a shirt, turbans, trousers, a hooded cloak, or a dress perfumed with saffron or Wars; and if
slippers are not available he can wear Khuffs (socks made from thick fabric or leather) but he should
cut them so that they reach below the ankles.
Sahih al-Bukhari Book 28, Hadith 22
