I worked for a woman exec decades ago. She complained that the dry cleaner charged x amount to launder/press her husband’s shirts, but more to launder/press hers. so she went to straighten him out about discrimination.
He explained that mens shirts fit on the presser - womens shirts, being usually smaller, had to be done by hand.
Mens shirts also tend not to have bust darts.
Or they didn’t used to.
Sigh.
