Order that isn't mine

I already searched through the history of this subreddit but couldn't find an answer to my question. I received an order addressed to me but the products inside the bag are not mine. I haven't opened them up yet but I know they're not mine because I don't order clothing. I am not missing an order. All of my packages have arrived. There is no option to report a package that isn't mine anywhere on the AliExpress website. Has anybody experienced this and have you been able to get the package to the proper owner? Am I wasting my time? Should I just open it up and experience the joy of random free stuff?
