All the outer jackets in this game- you can wear it outside your heavy armors - i think it’s intended to wore that way because this function is included in its description- but if you wear some large pieces of armor under it, the model will collide and the armor sticks out in cutscenes.
Here’s an example, with milanese brigantine and magdeburg pauldrons under a brocade jacket:
I think it doesnt constitute a bug(so I’m not posting in the bug section), but visually it’s a mess. Can you devs make the armor models not visible when wearing a jacket, and make the jacket appears bigger, enveloping the armor pieces? I would be so happy if you take your time and solve this issue.
