So Let's start with the delivery. The delivery is long, delayed by 20 days, although it is quite fast for the Alik, so thanks for not two months delayed. The shirt seems to be satin or it is synthetics, in general, I do not know. Looks fine, but it's because it's black. White will strongly shine through and look disgusting. It is a little small, I ordered 157 for growth, it seems, and it's good for me. In general, I advise the black shirt, good luck to everyone
