This hoodie was a simplistic and minimal. It can run true to size and still be loose as the hoodie itself is a looser fit rather than a fitted. That being said, I ordered a M although I'm usually a S in tops, but it fits comfortably without being too loose.
The reason I provided 4/5 stars is because of the quality. Every nominal product that I've purchased thus far has always exceeded my expectations - but this one was just a bit different. The hoodie itself is great, but there was much lint on the inside. In addition, the hoodie is a lot thinner in comparison to other hoodies I own from similar pricing. Again, although it looks fine, some of these things made me have different thoughts about the hoodie at this premium price point. I feel if these small things can be addressed, it would definitely receive the extra star.
