What does the Muslim say when he wears a new garment?

اللهُمَّ لَكَ الحَمْدُ أَنْتَ كَسَوْتَنِيهِ، أَسْأَلُكَ مِنْ خَيْرِهِ وَخَيْرِ مَا صُنِعَ لَهُ، وَأَعُوذُ بِكَ مِنْ شَرِّهِ وَشَرِّ مَا صُنِعَ لَهُ

O Allah, for You is all praise, You have clothed me with it (i.e. the garment), I ask You for its goodness and the goodness of what it has been made for, and I seek refuge with You from the evil of it and the evil of what it has been made for.
