This shirt is beautiful and true to American sizes. I sized up as i was worried it would run small, but it didnt. It was loose, and the fabric was light and comfortable. The blue color was beautiful as well. My only complaint was how long the shirt was. It was not flattering on me due to my short stature, and I don't think a size down would have helped that too much. Returning because it didn't fit me right, but I was very happy with the quality and color. I am 5 tall and wear a size 16/18 and ordered a 3x.
