Not the game, but the tailoring of clothes. Growing up in the late 50s, early 60s in the Midwest, I sewed a lot of my own clothes. Never did you make a garment without darts - how else would you make it fit? I mean this was the era of princess dresses. (What a great name!)
So I recently bought a blouse that fit amazingly well and it wasn't until I ironed it for the first time yesterday that I understood why. There were bodice darts and shallow darts in the back. It was made for a woman's body!
So I wondered if it was just the clothes I'd been selecting or if darts had disappeared. I googled it and all of the hits were either for vintage clothes (emphasizing the shaping by darts) or sewing.
