I just love the quality of NYDJ.  The fabric is always the best, resilient, perfectly shaded, and soft.  In my older pairs, I have realized that the color stays, whether it is pink, bright blue, black, or blue.  They stay true.  Plus there's the whole message that she should not touch these.  She doesn't want anyone to see the label, at least the middle school.

I also like the straight legs to make them look like regular work pants.  Something about bell bottoms just make them look too casual.

They are also supremely comfortable.  They don't look like jeans and they are more comfortable than jeans.  Win-win.
