I got the Kut jacket, and my mom and sister ordered it too. I have it in dark brown from last year and am thrilled to have it in black as well.
I got it last year in an XL and opted for an XL this year as well. I really could have easily worn an L if that was all that was available. It is forgiving/running large since you won't be fastening it up. I think that the arms in the L were snugger than I would like when I'm wearing layers (light knits/sweaters) underneath it, for ease of putting on/taking off with long sleeves, so I opted to size up. (I think the L is actually what was pictured on my post; visually there wasn't a lot of difference between them.
My mom and sister sized down (a M was too long in the arms for their preferences.)
