Large point of criticism, however: The blouse falls from relatively small. I usually always wear S or even XS, but am quite big with my 1.76m. Although you do not really stressed, but is pretty much the exact opposite of "loose fit". I had imagined quite differently, more in the direction tunic going. Since I lack a little more fabric length and, consequently, also of motion, I'll pass on the blouse on a smaller friend, who will probably have 10 centimeters less their enjoyment of the product.
Conclusion: Rather for something smaller, delicate people. Who does not attach importance to the "loose" but it may be as large, but narrow man wearing in size S. Otherwise, at least one size larger.
