How is SHEIN selling this legal?

I don’t normally go on SHEIN, I just sometimes browse to get ideas and this popped up Genuinely is this legal for a company to do this without artist or label permission? (I’m assuming Hayden’s team would NOT have given permission to SHEIN to make merch)? Does it fall under fair use???
