Good quality 819

This blouse for my son varsity physics seems very good quality, thick cotton and good finishes. What to see in use. The only downside is the choice of sizes. the proposed aid is useless and you have to start randomly. I took a size 3 and size 4 might have been preferable; too adjusted to the shoulders and sleeves a little too short. I have not requested the change because he needed it quickly. (For prospective buyers, my son measuring 1.85 m and is approximately 80 kg)
For the rest, fast and flawless delivery, as usual thank you Amazon
