I was so excited to get this coat in the mail because it looked so beautiful on Bluefly.com! This brand does XXS, so I was doubly excited to see how that would fit. Here is the stock photo from the site:

There are several reasons why I am returning it:
1) The collar is sooo much larger than in the picture - see how in the stock picture it's standing up a little so that less of the collar material is showing? In reality, the collar is not stiff enough to do that, so I have two large flaps for collars.
2) The sleeves are too long, but I was expecting to hem that. What I didn't expect was the tightness in the arms. The coat fits very well around the torso, so well that if it was in another style, I would have considered keeping it. I can wear a light sweater underneath. For reference, I wear a 00P, 0P, XXSP.
3) As you can see, the proportions of the coat are all wrong for this shortie. The coat hits me at the knee and gives the appearance that my legs are shorter than they are. The buttons are spaced for a taller person like the mannequin in the stock picture - see how the lower two are where the tummy is on the mannequin? On me, it is lower. Also, there is something about the flare of the skirt that isn't right.
The only great thing that I can say about this coat is that the wool blend is nice and soft. If you are my size, maybe 2 inches taller, with skinnier arms than I, you may like this coat. It just sadly did not work for me!
