Order 1 size larger.
Size: X-Large, Color: Blue White Plaid
Nice shirt. The size is not accurate by any stretch of the imagination. I wear size xl in shirts except for this one. An xl fits like a large. Other than that I like the shirt. I would've given it 5 stars if not for the sizing. I'll give away this one and order an xxl. Just order a size above what you wear and you'll be happy.

Satisfied with color and fit
Size: Small, Color: Light Purple
For the money, this is a good shirt. True, the material is a bit thin and there is a feeling of 'fragility' (loose threads here and there) but the color is nice, the texture is appropriate. The sizing is what I call "New American". I was a medium my whole life but supersizing has made me into a small. I haven't changed, Americans have grown bigger. I am six feet tall and a bit (180+ cm) and weigh 155 pounds (70kg and a bit). The small fits me just fine everywhere but the shoulders are just barely wide enough. If you have slightly wider shoulders but are similar to me otherwise, this may be too tight for you in that one place.

Fits too tight at waist.
Size: XX-Large, Color: Wine
Quality of product satisfactory, however size labeling incorrect. I ordered a XXL that is too tight at the waist. It should be labeled XXL Trim.
