a man asked the Messenger of Allah what clothes the Muhrim should wear? The Messenger of Allah said: "Do not wear shirts, or 'Imamahs, or pants, or burnouses, or Khuffs except if someone does not have sandals, in which case let him wear Khuffs, and cut them so that they come below the ankles. And do not wear any garment that has been touched by (dyed with) saffron or Wars.  

أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ مَا يَلْبَسُ الْمُحْرِمُ مِنَ الثِّيَابِ فَقَالَ رَسُولُ اللَّهِ ﷺ لاَ تَلْبَسُوا الْقَمِيصَ وَلاَ الْعَمَائِمَ وَلاَ السَّرَاوِيلاَتِ وَلاَ الْبَرَانِسَ وَلاَ الْخِفَافَ إِلاَّ أَحَدٌ لاَ يَجِدُ نَعْلَيْنِ فَلْيَلْبَسْ خُفَّيْنِ وَلْيَقْطَعْهُمَا أَسْفَلَ مِنَ الْكَعْبَيْنِ وَلاَ تَلْبَسُوا شَيْئًا مَسَّهُ الزَّعْفَرَانُ وَلاَ الْوَرْسُ  

a man asked the Messenger of Allah what garments we should wear when we enter Ihram. He said: "Do not wear shirts, or pants, or 'Imamahs, or burnouses, or Khuffs unless someone does not have any sandals, in which case he should wear Khuffs that come beneath the ankles. And do not wear any garment that has been touched by (dyed with) Wars or saffron.  

أَنَّ رَجُلاً سَأَلَ رَسُولَ اللَّهِ ﷺ مَا نَلْبَسُ مِنَ الثِّيَابِ إِذَا أَحْرَمْنَا قَالَ لاَ تَلْبَسُوا الْقَمِيصَ وَلاَ السَّرَاوِيلاَتِ وَلاَ الْعَمَائِمَ وَلاَ الْبَرَانِسَ وَلاَ الْخِفَافَ إِلاَّ أَنْ يَكُونَ أَحَدٌ لَيْسَتْ لَهُ نَعْلاَنِ فَلْيَلْبَسِ الْخُفَّيْنِ أَسْفَلَ مِنَ الْكَعْبَيْنِ وَلاَ تَلْبَسُوا مِنَ الثِّيَابِ شَيْئًا مَسَّهُ وَرْسٌ وَلاَ زَعْفَرَانٌ
