I've wanted to get better and more used to working in Marvelous Designer for a while now, so I decided to take the time to do that.
I created all pattern pieces and sewed them accordingly in Marvelous. It took some time to get the right look and drape on everything, but I'm happy with how it turned out. When the shape and silhouette was done in Marvelous I added smaller folds and seam details in Zbrush. I did the retopology and UV-mapping in Maya. After that I worked on the texture and stitching in Substance Painter. Finally I rendered the coat in Marmoset Toolbag and I used this guide to help me with the set-up of the coat material:

By the way, this is my dream coat which I hope to sew in real life sometime.
