Doo.Ri Chung’s had quite a week. The designer made headlines this weekend when the First Lady, Michelle Obama, wore a purple gown  from her spring collection to the White House’s state dinner for South  Korea and today, Macy’s announced she’d be the next designer to design a  collection for Impulse. Chung is the latest of five designers that Macy’s has asked to  collaborate with their Impulse department, hoping to attract a younger,  design-hungry customer. First was Kinder Aggugini, then Matthew  Williamson and Karl Lagerfeld. Giambattista Valli’s cocktail dresses  hit stores next week and in February, Chung’s designs will take center  stage. The collection includes plenty of jersey and draping—Chung’s  specialties—as well as leggings, trench coats and blouses and it’ll  range in price from $39 to $159. Chung told WWD,  “The customer is very different from whom we’ve catered to before, but I   really didn’t have to adapt. Macy’s wanted to keep the design level   high. I didn’t feel the challenge was very different.”
