yes, the WWM trench is the one on Yoox, I came across a few last year but all in large sizes so I was familiar with the item, I was very happy to get it in a smaller size this time around. The outside fabric is heavy cotton twill, and there is also a inner wool lining that is not removable so it is very warm. I highly recommend it and I feel that it is more worth the current price. It's hard to describe it exactly but if you are interested in it I definitely would buy it and check it out in person and return it if necessary. Though my bet is that if it fits you, you will definitely keep it. There is also a black one for sale on Yoox.
Also the Gap jacket is surprisingly slim cut. I never would think to look there but I happened to see it in a photo spread in Details magazine and decided to take a chance on it (I was pretty much desperate as I've been wanting a Harrington for the past year, and Baracuta jackets, even the slim fit ones fit me like crap). The Gap one is definitely worth a look.
