ARE THESE SCAMS?!?

Ariel

Sorry for the aggressive title but i need some advice pls 😂

I keep seeing sites like Romwe, Shein and Fashein popping up everywhere and the clothes look so nice but I'm worried it's a scam! I've looked up reviews but it's not a clear yes or no.

If anyone has used these websites before or something like it please tell me what it was like and if it's worth spending money on
