How much for a bikini set?

Has anyone bought a bikini set from Shein, Temu or Aliexpress? How much was it and do you think the quality was good enough?

I am trying to convince a friend to start her own swimwear line, and I want to know how much people are willing to pay for a bikini set. Shein, Temu and Aliexpress have some cheap bikini options, but are they better quality than the high end brands like Wickedweasel, BoutineLA etc? Also, where do you all get your bikinis from?
