I am between a size M and L in button-down shirts because I have broad shoulders and a larger chest, 36DD.Some reviews say you have to size up 2 sizes but that is not true at all. The large was too big for me so I had to return. I liked the shirt, so I ordered the medium but it's too small in the shoulders and chest, I cannot move my arms at all. The large was too big to the point where it was baggy and did not look good but the medium is too small. I wish there was a true happy medium.I gave this shirt 4 stars only because I wish it was a bit longer. Overall, great fabric and quality.I work in the food industry as a server and we have to wear black button ups. I’ve had many servers ask where my shirt is from because they say that it looks crisp and fitted. It does the job and looks nice and is pretty well fitted to my body. Would definitely recommend.The material is soft and I purchased it for work.Nice shirt but, runs smallBest button up work shirt I have ever bought. True to sizeFits just right, very comfyLove the color and texture . Ordered a size up and glad I did! I just can’t get the fold wrinkles out! I’ve washed and line dried, washed and dried on low, washed and ironed on low and the folds seem permanent !
