Depends on the college campus. Thre are lots of fit, slender coeds, my daughter and her friends/classmates among them.
My daughter goes to Lipscomb. She is thinnish. 5’3” 105 pounds
Her sorority sisters are overweight....at least 75% of them.
I just went thru Ole Miss this weekend and actually ate at Newks (southern Deli chain) and walked around campus (where I went)). The girls are heavier...not Wal Mart heavy but I’s say 10-15% thicker.
Myself and DC2000 went there in the 70s and the women were nearly all slender and fit and many were gorgeous. They are still pretty but just fatter.
And there is a lot of pressure there to look good. didn’t get the chance to review but I’d bet most Tri-Delts, KDs and Chi Omegas at Ole Miss are still fairly proportional...and often blonde...lol
I bet SMU in Dallas or University of Alabama, the schools most resembling Ole Miss demographics are similar today too.
