Rosé Pistol Handford Nylon Jacket

I got a medium and im having the same exact issues with this jacket. I feel like I might rip the jacket if I reach my arms in front far enough. Everything is fine when I have my arms down. It's a shame that the fitting is off. This could've been a great jacket and I loved the interior design.

Mine arrived yesterday, some thoughts: Usually i have size L, however for jackets sometimes even M fits me. I ordered in L however to be sure. And while the overall size seems good for me while standing normally, there is a huge resistance in the elbow once you flex your arm enough, e.g. when closing the zipper or collar. Also if you raise your arms the jacket raises with them, just as you know from suits probably but much more. I did never thought that you could fail that much on a jacket, never experienced before. Conclusion: Totally inflexible, but fitting quite well if standing still with arms down. Cannot recommend for anyone who wants to move their arms.
