The interviewer wants to hear that you enjoy fashion and are familiar with famous designers. We recommend that you visit Nordstrom's website before your interview to get familiar with the designers they are currently offering. Merely pick the designer whose style most appeals to you, and share it with the interviewer. Be sure to mention why you like that style too. For example, you might suggest that you like Alexander Wang's fashionable handbags because they are always timeless and elegant.
"Right now, my favorite designer is Ted Baker. I love the classic elements mixed in with the out-there print, on many of the clothes and accessories. I know that you have many great smaller designers in your stores as well. Which ones are your favorite?"
