Two sightings today.
Lunch in a restaurant, a young guy, certainly no older than in his 20s, was wearing shorts made out of sweatpants material (it was an unusually warm day). He walked by my table three times, and each time the outline of his briefs were clearly visible through his shorts.
At dinner, a young guy came in with his family, wearing a sweatshirt. Before sitting down, he pulled off his sweatshirt. His t-shirt was not tucked into his gym pants and rose up as he pulled off his sweatshirt, revealing the waistband of white briefs.
Who says that young guys don't wear briefs!
