Invocation when putting on new clothes

"اللَّهُمَّ لَكَ الْحَمْدُ أَنْتَ كَسَوْتَنِيهِ، أَسْأَلُكَ مِنْ خَيْرِهِ وَخَيْرِ مَا صُنِعَ لَهُ، وَأَعُوذُ بِكَ مِنْ شَرِّهِ وَشَرِّ مَا صُنِعَ لَهُ".

6. 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.
