F*** me that's so confusing! Different store indeed, but still! the link you shared, the pictures with the dude are clearly stolen. I do my best not to buy anything from stores who use these pictures because it's a red flag. Ditto with stores with random number names, like store209384828828483, these are pop up shops that are glorified pump and dump schemes. They're always brokers, basically drop shippers, and they're unable / unwilling to send actual pictures of the stuff they sell. The real items essentially never resemble the pictures they use (steal).
Now that being said, this link from eg, from the store you bought from
https://nl.aliexpress.com/item/1005006464078201.html, looks very similar / identical to what i ordered in terms of fabrics (see a collage of my jersey for reference). Here again, ignore the stolen photos with the androgynous dude, i'm talking about the item photos which is clearly made by them / a related party.
Maybe what you got is a case of quality fade, where they make good jerseys, but also shit ones, and over time / randomly they ship shitty ones to save 1 buck? It's in the culture to constantly play games to save 5 cents, so let's not pretend it can't be a thing.
Or you have a very different experience of what's a good jersey and what feels like plastic, i guess that's also plausible?
