Ordered the "USsizeM=TagsizeXL" in navy blue, and I am usually between sizes M & L (5'6", 140, 36C). At this price point, the shirt quality is as expected -- material is slightly translucent (requiring an undergarment) and just a bit rougher than a true chiffon. The tailoring is good and the collar is stiff enough to holds its form and not require ironing. I plan to re-purchase more colors!
