I have been buying this brand of shirt for almost 10 years. This version I bought March 2018 was similar to the last version I bought. The edges were serged instead of folded under and topstitched. Which I don't mind. It was much tighter than the old ones. I bought the same size I always do and it fits at least a size smaller. Maybe 2 sizes. I don't mind since I wear it under clothes, but I wouldnt want a shirt that tight if thats all I was wearing.
