Malik related to me that he heard that Umar ibn al-Khattab saw a female slave belonging to Abdullah ibn Umar ibn al-Khattab. She was dressed like free (non-slave) women. He went to his daughter Hafsa and said, "Didn't I see your brother's slave-girl dressed like a free (non-slave) woman walking among the people and causing trouble?" Umar disapproved of that.

وَحَدَّثَنِي مَالِكٌ، أَنَّهُ بَلَغَهُ أَنَّ أَمَةً، كَانَتْ لِعَبْدِ اللَّهِ بْنِ عُمَرَ بْنِ الْخَطَّابِ رَآهَا عُمَرُ بْنُ الْخَطَّابِ وَقَدْ تَهَيَّأَتْ بِهَيْئَةِ الْحَرَائِرِ فَدَخَلَ عَلَى ابْنَتِهِ حَفْصَةَ فَقَالَ أَلَمْ أَرَ جَارِيَةَ أَخِيكِ تَجُوسُ النَّاسَ وَقَدْ تَهَيَّأَتْ بِهَيْئَةِ الْحَرَائِرِ وَأَنْكَرَ ذَلِكَ عُمَرُ ‏.‏
