While a traditional university may or may not be worth the cost—college enrollment fell 2 percent this year—there's one school of higher learning that truly pays off (without leaving coeds in debt). What is this elusive free school, you say? Tyra Banks University. An easy five-day course, TBU offers lessons on two-minute makeup, diagnosis of the Vajarmpit, Boobs 101, and the secret to finding your highest-earning haircut. Here, Tyra Banks, the original multi-hyphenate, the master of reinvention, discusses breasts in the workplace, visible nipples, and how to dress for your cup size.
