In the September 23rd issue of the magazine, the Style Issue, Rebecca Mead profiles Andrew Rosen, the C.E.O. of the fashion company Theory. The company found success in the nineties by making stylish and comfortable work clothes for women. Here, Mead talks with Susan Morrison, who edited the issue, and Sasha Weiss, the literary editor of newyorker.com. They discuss the effort it takes to look effortless, how the codes of dressing for work have changed over the years, and why people who work at The New Yorker are sometimes referred to as "the Waltons." Also, Ethan Kuperberg has an S.A.T. test for adults.
