This coat is absolutely gorgeous. It has a very flattering shape and the material and make are excellent quality. However, it's worth being aware that it does run extremely large. According to the Will's size guide, I should be a medium (for reference, I'm a UK size 10 and an EU size 38). I bought a medium at first, and it was comically oversized. I was able to return it for a bigger size very easily - customer service didn't reply to any emails, but their return system is good enough that that didn't matter too much. The size small is still on the generous size but fits nicely.
The only other thing is that this coat only has one set of functional buttons, which did make it hard to keep it closed against the cold. I took it to a tailor and had it adjusted to have three functional sets of buttons. The tailor commented on how good the quality of the coat was, and it's now far far the best coat I've ever had - well worth the fuss with the sizing and the tailor!
Very pretty and smart looking coat, soft and feels high quality.
