As it happens, I have that LE coat in the blue (just got it yesterday!) and I like it more than I expected. I had 2012's version of this coat in violet and liked it quite a bit, but a large weight loss necessitated new... everything, really. I'm 5'4", 163 lbs, 36DDD for size reference; I wear a 10 or 12 depending on the garment.
The color, first: it's actually quite nice, like a bright navy, more of a midnight blue without the yellow undertone that can come with midnight. The Smokey Plum LE is doing this year is too warm for my coloring but is very rich looking in person.
On me, the length is about 4" below my knees. This is desirable for me in this type of coat; I'm using it for walking-places-outside-in-Milwaukee-winter purposes, not a dash from car to grocery store, so I want for there to be little to no gap between tall boot-tops and coat hem. I wear a kelly green wool overcoat for less frigid tasks.
I bought the medium, my regular LE size. It's a little roomier than I prefer--there's space for a couple of strata of winter-layering underneath--but in hard subzero wind chills I find that I am warmer in a coat that isn't extremely fitted. If you are less busty you may find that going smaller would yield results that were more streamlined and flattering.
I don't care for hood fur--it just statics up my hair--so the absence is a selling point for me.
