Jane x Jazz camisa negra

I’m really happy with my Jane x Jazz shirt that I have worn only once or twice for the moment but that will clearly be very good for the mid-season or more if I find a vest in which the sleeves pass. This is my first Ready To Sew pattern and I am pretty convinced by the brand. It’s solid.

However, I have a fit issue at the upper arms / shoulders on certain movements. You can see more about that problem on my blog : https://miio.org/sofar/gb/aiguille-ciseaux/coudre-chemise-jane-jazz-ready-to-sew
