For '80s buffs looking to recall the heyday of the brain, the beauty, the jock, and the rebel, Universal Studios has introduced a line of shirts inspired by Brat Pack flicks The Breakfast Club and Sixteen Candles -- ''two classics that teens still love today,'' notes Universal marketing's Tim Rothwell. Emblazoned with such images as Anthony Michael Hall pleading with Molly Ringwald, ''Can I borrow your underpants for ten minutes?'' the tops (at Hot Topic stores and hottopic.com, $19) have attracted nostalgia-loving celebs such as Juliette Lewis and Brooke Burke. Next up: Back to the Future shirts. Go, McFly!
