Would anyone who has the J Crew Lady Day coat -- preferably the one with Thinsulate -- be willing to describe the fit? Did you buy your normal size? Did you find the shoulder fit snug? What about the bust, and how did your winter clothes fit underneath?

It used to be that dressy winter coats started at a size 2, and even the smallest among us found a 2 quite small enough. With J Crew now offering a 0, a 00, and a 000 in addition to a 2, I'm not sure what to think and I don't want to go through a tedious cycle of purchases and returns, so I turn to the generous ladies of YLF.

Any guidance would be much appreciated.
