For the record, the Southdale J Crew also still had a bunch in various colors and sizes, mostly 0, 4, 10, and 12 from what I could see from my quick glance in that area.
IMO no, only because I own three (one is a 2, one a 4P and one a 6) and they all fit exactly the same. I can't order from J Crew without trying things on, their sizing is wildly inconsistent--at least for my body.
I found that out today. I tried on a 12 in the hot pink and it fit great then a 12 in a cream and i couldn't get it zipped.
