Dua for Wearing New Clothes

اَللَّهُمَّ لَكَ الْحَمْدُ أَنْتَ كَسَوْتَنِيْهِ أَسْأَلُكَ خَيْرَهُ وَخَيْرَ مَا صُنِعَ لَهُ وَأَعُوْذُ بِكَ مِنْ شَرِّهِ وَشَرِّ مَا صُنِعَ لَهُ

Transliteration

Allaahumma lakal-hamdu 'Anta kasawtaneehi, 'as'aluka khayrahu wa khayra maa suni'a lahu, wa 'a'oodhu bika min sharrihi wa sharri ma suni'a lahu

O Allah, for You is all praise, You have clothed me with it, I ask You for the good of it and the good for which it was made, and I seek refuge with You from the evil of it and the evil for which it was made.
