Wear whatever you want, as long as you avoid extravagance and vanity

It was narrated from ‘Amr bin Shu’aib, from his father, that his grandfather said:
“The Messenger of Allah ﷺ said: ‘Eat and drink, give charity and wear clothes, as long as that does not involve any extravagance or vanity.’”

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، أَنْبَأَنَا هَمَّامٌ، عَنْ قَتَادَةَ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ قَالَ رَسُولُ اللَّهِ ﷺ " كُلُوا وَاشْرَبُوا وَتَصَدَّقُوا وَالْبَسُوا مَا لَمْ يُخَالِطْهُ إِسْرَافٌ أَوْ مَخِيلَةٌ " .
