Hisnul Muslim 6

When wearing a new garment

اللَّهُـمَّ لَـكَ الْحَـمْـدُ أَنْـتَ كَسَـوْتَنِيهِ، أََسْأََلُـكَ مِنْ خَـيْرِهِ وَخَـيْرِ مَا صُنِعَ لَـهُ، وَأَعُوذُ بِكَ مِنْ شَـرِّهِ وَشَـرِّ مَـا صُنِعَ لَـهُ

Allaahumma lakal-hamdu 'Anta kasawtaneehi, 'as'aluka min khayrihi wa khayri maa suni'a lahu, wa 'a'oothu bika min sharrihi wa sharri ma suni'a lahu.

O Allah, praise is to You. You have clothed me. I ask You for its goodness and the goodness of what it has been made for, and I seek Your protection from the evil of it and the evil of what it has been made for.
