Hmm. He oversimplified some things, I think. Hepburn's tough approach probably kept her from being preyed upon by Weinstein types, because she and Spencer Tracy certainly got along. Women and men did dress up more to go out, in their special going out clothes, but the housewives I remember from the fifties definitely didn't have the Mrs. Cleaver look around the house, and ditching the tie was the first thing after work. When synthetics came along and clothes were mass produced, they got simpler and simpler and it was fine because people could afford more daily wear. They didn't care about the relatively poor quality because it was cheap and since not enough cared the trend accelerated. Then the victim crowd came along with the fat is healthy stuff--that is a SJW problem more than a fashion trend.
