Another older fart here. As others have said, you look good! Wearing it a few times to get used to it is a great tip.

Especially since they are inexpensive clothes, if you need to clean them, wash and dry them carefully. Dunno your setup, but make sure the washer is set to cold or the low side of warm. Dry medium and don’t over dry. If the washer and dryer have a “permanent press” setting, that should work ok. Immediately hang them; don’t let them sit in the dryer.
