J. Crew's Cashmere: Is it for me?

I have come across a few comments here and there (in different posts) about the quality of J. Crew's cashmere. I personally do not own any 100% cashmere sweaters (only partial cashmere). So my knowledge is limited. (As I mentioned in a previous comment from a post: Although I would love something from their cashmere line, I find it a bit too expensive for me right now.)

However, I would like to open up "the floor" to all of you in a single, easy to find post...

So, for those who have questions about J. Crew cashmere please feel free to ask here. For all those who have first hand experience with J. Crew cashmere, please help answer these questions. We can all benefit from our collective knowledge!!!
