The Prophet (peace be upon him) offered the following supplication upon wearing a garment for the first time. He would state what item it was - turban, shirt, waistcloth… - then say:

O Allah! Yours is the praise, as You have clothed me with this. I ask You the good of it, and the good that it was made for; and I seek refuge with You from the evil of it, and the evil it was made for.

(Allâhumma! Lakal-hamd, kamâ kasawtanîhi. As'aluka khayrahu wa khayra na suni`a lahu, wa a`ûdhu bika min sharrihi wa sharri ma suni`a lahu.)

This supplication is narrated in Sunan al-Tirmidhî (1689) and Sunan Abî Dâwûd (3504). It is an authentic narration.
