Back in the Dark Ages, when Ivan attended college, nobody at my school, did this. I think too, that many a 'lounge pant' these days, looks much like a pajama bottom. In my day, super short cut-offs, were in style. I mean VERY short. For both sexes.
What I'm seeing at my alma mater, is a plethora of very brief tops being worn by college coeds. Deeply cut, bare back, with the most fragile of straps tied behind these young ladies' necks. Distracting, to say the least. Strapless tube tops and bandeaux, as well. Good thing the young men don't wear those super short cut off jeans, anymore.
