IDK. Attraction isn’t best gauged looking at still pictures. Much of being “well-built” is in how people move and how the pieces of the figure attach to each other and move together.
Over all I agree with Cartoons Hate Her here that there are men for every type of figure, but just look at the difference in the pics below between the way the breasts sit on these marble statues in the beginning and then the way she represents breasts in the bulk of the article. This “Kardashian” figure isn’t attractive because it looks saggy and old, not because of the technical proportions. You can have a good waist to hip ratio and still have the curves kind of sit wrong on the body, and men will prefer smaller curves that are taut to larger curves that are droopy or dumpy looking. Health and vitality is more than measurements. It has to do with how muscle and fat move on the frame, too.
CHH’s mockup of the Kardashian figure looks 45, which could also be why it wasn’t preferred lol
