1, look at the NBA logo first. This logo is embroidered by computer, and its workmanship is very fine. However, often the cottage products are full of loopholes. From the modeling point of view, that person's embroidery is a bit inappropriate and not full at all.
2. Look at the workmanship of the embroidered number and name of the jersey. The workmanship of the fake jersey is definitely not as fine as the genuine one. The reason is that the production of fake jerseys only requires quantity but not quality, while genuine jerseys require not only quantity but also quality.
3, the fan version of the authentic jersey is generally shorter than the back film. And the fan version of the jersey will have a logo under the NBA logo.
5, genuine jerseys are different when embroidered by computer. Computer embroidery will require players' names and numbers to use black paper, so that the reverse side is more beautiful. For the NBA logo, white backing paper is generally needed. But fake jerseys, no matter the number or logos, are lined with white paper.
