Got it yesterday - indeed a great shirt. Love the fabric (that looks a little bit like linen but is a beautiful cotton fabric).
I am 184 cm and slim - took size L, which fits perfect. A little bit snug / form-fitting whereas the collar width is relatively bigger than you'd expect from a size L (I usually wear a collar size 16", and this shirt has got a 16.7" collar size).
Nevertheless fit is great and this shirt deserves to be called "The Great White".
With kind regards,
Johannes
