If I truly believed, that this would be waiting for me under the Christmas tree, I think I would look forward to Christmas a whole lot more, than I do now. Lavenham jackets - the regular ones - are my go-to jackets and I have had more than a couple throughout the years. I don't know, what it is about them, but they fit great and keep you just warm enough to not get toasty, but never get really cold either. I just bought a waxed version and I'm sure, that it will be my new favourite jacket.
This blazer however would fill a hole in my wardrobe. Looking slightly more dressed, while remaining warm and comfortable. Furthermore it has three-buttons, which suits me the best, I think. Again personal preference.
Only thing I dislike is probably the inside colour, but it might surprise you in person, which you can at Present London.
When I started buying jackets from Lavenham some years ago, they still went by the name Lavenham Horse Rugs. I quite miss that.
