Thank you, Ed. Somehow I was thinking that raising the gorge would put it on top of my shoulders, too high, but couldn't figure out why it still looked "low" - the size of the notch seems to be the cause indeed. I believe they offer different, more closed notches, that I could try.
Would you still make the lapels narrower if shoulders were to be extended on a new jacket? This pose doesn't show it, but IRL I believe the jacket doesn't fully disguise my pear shape, so I was thinking of adding half an inch to the collar felt to sleeve cap measurement.
I actually did ask for 10 cm lapels with this jacket, but the factory made them 11 cm (I'm still wondering why), which is almost that half inch difference.
I'd have to see you in person or a picture of how extended the shoulders. I don't know what size you are, looking at the pic I am guessing you have a 100-105 cm chest and 44-47 cm shoulders. I would stick with 9.5-10cm lapels. The other thing though, is that if you are keeping the roped shoulders, I would go with straight lapel points as opposed to the rounded ones, I think that is more coherent with those shoulders. I think your rounded lapels would look good with natural shoulder/unconstructed type jackets.
