I still don't like how the shoulder lifts up at the sleeve joint please ask them to press it down.
Is it just me, or do a lot of Mina's jacket's have slightly concave shoulders (vaguely pagodo-like)?
Not pagoda style but concave, yes. There is a discussion of this, complete with red lines, in a NSM thread Edmorel started. Maybe it can be found and posted here.
This shape/expression won't show up on the try-on garment as much as in the finished jacket.
To me, this is the biggest draw to Mina's jackets. This is the hardest shoulder to make and very few tailors are able to execute this very well. Most don't want to try. I've spent years seeking tailors who make this to learn from. IMO this shoulder gives the most freedom and movement to a jacket and sits/stays on the shoulder the best. This is a thing of beauty! If you don't care for the aesthetic, I'm sure she will accommodate with a different profile of shoulder but asking to flatten and press it down is like being at the best steak house in town and putting ketchup on your steak. As this shoulder isn't seen much I can see how it would look unnaturally different to what is the more common ways of shoulder construction.
