Musar su Salmi 57:9

ועשו בגדי קודש. Just as proper clothing bestows honour and dignity on the body of the wearer, so a body in proper condition bestows honour on the soul that inhabits it. This is the meaning of the words: בגדי קודש לאהרון אחיך לכבוד ולתפארת, "sacred vestments for your brother Aaron for dignity and adornment." According to this the word לכבוד alludes to Psalms 57,9: עורה כבודי, "Awake O my dignity!" It was in such a context that the famous Rabbi Yochanan described his clothes as מכבדותי, "that which bestows dignity upon me" (Shabbat 113). Whenever a person gets dressed he should train himself to think that he covers not only the nakedness of his body but also that of his soul.
