The company is not kidding, this is a unisex shirt but I was scared to order a smaller size and got my normal size medium, which I wear in every other unisex shirt I buy. It's longer than typical unisex and fits more like a large, especially after it stretches out a bit while wearing. However, the sleeves are close to normal length for a medium and I don't think I would have been as happy with a small. That being said, this shirt is crazy comfortable, has a bit of stretch to it and washes up very well. Don't even care that it's bigger than I prefer, still give it 5 stars because it's an amazing shirt.
Awesome shirt! Great design and very high quality. Love the vintage look.
