Quality? Yes...
Stylish? 
I have the dress and the sleeveless top from Milk, and they are very comfortable and for casual around-the-house wear they're stylish enough. I am fairly short (5'2") and shorter up-top and the peek-top blouse rode too low on me. The clothes seem to be cut for someone in the 5'5" range - pretty standard. I felt the tops ran true-to-size, a bit large in the waist.
I have also used Old Navy's nursing wear, which is hit-or miss. It's not horribly stylish... but it works for around the house.
I do not NIP, so no use there.
