I got this for my partner for one of his birthday presents. He usually gets shirts in a large as a rule, but the listing for this one said to follow their size chart. According to their chart a medium was the way to go so that is what I orderedMy partner wears black almost exclusively. He has very few shirts that aren't black and they're usually only worn around the house. This shirt is perfect for him since the splash of color is only on the insides of the cuff and the collar. The medium was also a perfect fit for him. He gave it a good moving around in to make sure. He thought the sleeves were a tad short, but when not rolled up, they extend to his wrist bone. A perfect fit. He also likes the material and says it feels nice. I'm really pleased with the shirt too since he loves it and it's super reasonably priced.
