I known / seen and own along with my girlfriend many pieces of harnden.
But well made is not exactly a way of describing his work i would say.
It certainly is made with a different approach to anyone else which contributes to the whole look and feel of the garments. But the seam/stitch work is very poor, buttons often come off, button holes are opened in a very rough way, there are far greater quality shoes out there. However i feel all these issues he chooses to reject or ignore.
The first coat and the second mac are beautiful (the 2nd mac i think is new, something i haven't seen before) the rest is very similar to previous collections/buys ; he never changes (nor should he).
On a different note, to make Harnden wearable the easiest way is with denim, his fabrics seem to work with the weight of denim.
