I wear 2P and purchased this in XS. The shoulders, chest, and waist are snug (when I wore a thin t-shirt under). I'm 5'3" and the sleeve length is good ('love the ribbed cotton cuffs at the wrists), and the length is about six inches above my ankles (which is good for me). The weight and warmth is moderate (not high) for a long down coat. I'm a weather wimp and freeze easily. But I'll probably keep this, since it is a reasonably good value at nearly half-price. I personally wouldn't pay full price for the cold-weather functionality of this coat (as I've had warmer, thicker long down coats; e.g., Eddie Bauer makes a more functional one, rated for low temps). However, if you are looking for a more slimline, more fashionable down coat - this may be for you. It's hard to look slim in a long down coat, but my profile is "thin" in this! I'm not crazy about a piece of real fox hanging onto my hood, but it does add a bit of fashion pizzazz. The fox part is removable, and the coat looks fine without (albeit more mundane). The material and construction seem moderately-high quality. The material makes moderate noise when the sleeves rub against the coat's sides (like loud leg nylons). I wish the zippered pockets were lined with a bit of fleece material to make them more cozy, but I guess they wouldn't be so super-flush, if so? The hood is designed such that it seems like it would actually stay on my head easily, without needing to snap or zip all the coat way up, which is nice if you have to dash through a bit of rain.

This coat will give me another reason not to gain weight, as five pounds would definitely show with this zipped up at the waist! I would seriously consider sizing up if you are: 1) between sizes, 2) planning to wear thick clothes under, 3) apple-shaped (relatively large waist), or maybe 4) broad-shouldered or large-chested. It's nice when return shipping is free (but be careful if they are running out of the next size up if you hope to exchange).
