Did you experienced weird sizing with Stephan Schneider?
I bought the Armenian Blue Wool jacket in size 3 and it is perfect.
I tried a shirt in size 4 and it was great. I tried another shirt model but the good size was 5 on this one.
I also tried a Artik knitwear and the perfect size was 4.
So it seems that I wear randomly between 3 and 5 with Stephan Schneider... that makes online order quite hard
