I have royal blue with short and long sleeves. I use them as a mechanic and they look very professional. Powerful but not too hot. The size fits right, maybe a little small. I bought an L and I'm 200 pounds, 5ft 5, 17in neck. I always leave the top button undone. After a couple of hot washes the color is still vibrant and they've shrunk a bit. Came back to AMAZON and bought a full set of these uniforms. I LOVE IT! UPDATE 7/2021: I really like these shirts. The royal blue is what I use at work as a motorcycle mechanic. They've worn for well over a year with weekly washings in HOT water and lots of SHOUTING to get rid of black greasy and oily stains. The color remains bright blue. Very little shrinkage after my first week. They're better than men's uniform shirts. I bought them in other colors to wear at home as casual shirts. And they look very beautiful in all colors. The photos on Revain don't match the colors at all. RECOMMEND IT! GREAT!
