I've been emailing back and forth this week with a rep from Jcrew, who is helping me determine which size suit to order in the petite suiting. I still haven't decided (need to get the tape measurement out and compare with existing garments) but I just wanted to post a public kudos to them here.
I asked for detailed measurements of the garment laid flat - so I could compare what I already know fits in my closet - and they gave it to me within a day - for three different sizes. This is fantastic service and I'm really hoping one of the sizes is close, so I can order.
My only worry - looking over the measurements provided - is that the back rise for the slacks is going to be all wrong for me. I know 11" back rise works best, but for the three sizes given (0p, 2p, 4p) the back rise is around the 14" mark - great if you have a butt, which I don't. I wonder how easy such things are to alter? I am willing to alter.
Even if it ultimately doesn't work out for me, I want to say that my previous complaints about Jcrew service have gone away.
