And this, kids, is where "dad jeans" were born. The only difference is, back then, when worn in the style of Zack Morris on Saved by the Bell, they deemed you the ultimate heartthrob. Especially when combined with billowy, tucked-in button-ups, Member's Only color-block jackets, Sun-In bleached hair, and anything else splashed in garish primary colors. Take a look at your teenage scrapbook—this guy was secretly your style icon.
