I have ordered the duffle coat in size 52 (German). Came the British size 42. I am 175 cm tall and powerfully built, to me is the perfect duffel coat! He walks me to just above the knees, as it should be the classic duffle coat. For pants, I need the rest of size 56 and W38, as my imagination stature. A small-built man of 175 cm is large so probably needs more 48-50 (German size).
Well for quality. I am very enthusiastic about what you get for 250 euros. The jacket is well processed, keeps very warm and looks like a classic duffle coat has to look from England. Ie. He has a straight cut (not fitted), no zip, toggle closures made of buffalo horn and a hood. Two outside pockets and one inside pocket completes the whole. It can also be at the top close to the neck (with buttons), then you would need also no scarf. He also has a very nice classic pattern inside.
With a casual chinos or jeans are fine, making it very elegantly dressed. I recommend, however, before times in business to attract a duffle coat, to see if something is one at all. If so, you can do here is definitely nothing wrong, a strong buy recommendation from me!
