I've seen other reviews suggesting I go up a size so I did. I'm currently between medium to large, so I went for XL to be on the safe side. It was too big. I returned the product and ordered a large one. What. is working. It's a bit long but fits my body perfectly. Remember this is a slim fitting shirt so it will be comfortable in your correct size. I highly recommend going up a size unless you want your shirts to be a little tight. That's why you're probably looking at fitted shirts in the first place. Overall a good product.
