I think the shrink-proofing is good.
The t-shirt is a Printstar 5.4oz. As the tag says "pre shrunk", this item is 100% cotton, but it is shrink-proofed so you don't have to worry about it shrinking after washing. It is not too thick, not too thin, and just right in terms of comfort. The body length is a little long, but I think the balance of the body width, sleeve length, and body length is good. It is a little big, so I think an XL would have been fine. The print is also well done. I think it is attractive to be able to purchase an original printed T-shirt for 2,200 yen (tax included). Moreover, shipping is free. There was almost no difference between the size chart and my own measurements, but when I bought a 5.0 oz regular fit T-shirt from the same manufacturer, there was a big difference between the size chart and my measurements. It was smaller than the size chart. When selecting a product, there are many choices and time consuming because the fit varies from product to product. Furthermore, I would like you to correct the error between the listed size chart value and the actual value. We are considering the product for commercialization, but have not been able to make a decision. I think it would be good to have a service such as free sample lending so that we can check the color and size of the rated products.
