Wearing new clothes:

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

"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.”.
