The way it works is that you tell them what you're traveling for and then you get something like a "spring/fall x smart casual" variety pack delivered to your hotel or Airbnb.

You're both using clothes that might otherwise go to waste and you're reducing the amount of weight that you're traveling with. (You still need to bring your own underwear.)
And this could add up:
