Oh Gosh............
I am going to out myself here on some level........
My mother had a woman that ironed for her. She was Mrs. Hopkins, but "Hoppy", to me. She did all my father's shirts, (until the late 60's, and then they were done by the cleaners
], all blouses, all trousers and all sheets.
She taught me how to iron everything from briefs, bras, socks and sheets! For many years I ironed on and off. At this point in life, I iron, NOTHING, due to fact I have a wonderful laundry that creases, presses and folds everything to my liking.
During my collage years, a grandson of the VanHeusen shirt company told me, no matter what, wash my shirts and then send them to a professional laundry. I do this to the day. He also said, turn polo, and polo like shirts, inside out, with all buttons, buttoned, through the wash and dryer, then turn them back inside and hang them.
I've done that for years and still do it. Fading is minimized and then look good for a long time.
