Do you have specific names, BC, or items that interest you?
The Nordstrom house brands are Caslon (marketed mainly to juniors, I believe or for casual wear); Halogen (more business oriented clothing with some trendy items). Halogen Collection has higher end. Zella is for gear.
I don't own any Caslon items or Zella, but the few Halogen items I own tend to be good quality for the price, sized on the generous side, i.e. I might need to size down from what I would wear in J. Crew or even Banana.
One of the nicer features is that Halogen often offers items in petites or plus sizes, so a wide range of people can enjoy the looks.
