I bought this jacket from Vertice London a little while ago and I quite like it (as does my wife, she's always touching it when I wear it). Will try to get a fit pic soon, but in the meantime I just wanted to give 10 Sei Otto a positive mention since they seem like a really good value to me (Farfetch has this jacket for ~$620 now, which seems like a steal).
The leather is quite thick and feels quite soft despite being calf - guessing they oiled it some (although it doesn't feel oily). The cut is very slim and looks pretty modern IMO. It has very high armholes and slim sleeves and the collar stands up well on its own. I usually wear a 48 and the 48 on this jacket fits very snug and slim. The lining is pretty thick and works well in cold weather.
The only thing I wasn't fully digging was the wool-blend lining extending past the hem. I know this is the major design feature of the jacket and it'll definitely work for some people but it wasn't my style so I took some scissors and trimmed it off. The look without it is kind of similar to the Attachment leathers that have a clean raw edge on their unlined leathers.
Ohya, the leather has a nice matte surface which I quite like compared to the normal shiny leather surface. Makes wearing a black leather jacket a lot less severe IMO. Anyone know what the treatment used to get this is?
