Nordstorms's Dress Code?

If you are working for Nordstrom's in Jewelry/Accessories or Men's Apparel, what is the dress code? Do you have to wear Nordstorm's labels? I'm interested in working there, and have an upcoming interview, but alot of my "business casual" wear is from Kohls like the J Lo line, H&M I actually don't really have any of Nordstrom's brands clothing to wear right away. What is the company discount like? I'm just wondering what to expect. I suppose I should of asked this for my interview, I'm planning on wearing a dress by JLo-Kohls, it's a very beautiful sheath, but not sold at Nordstrom's of course!
