Karl Lagerfeld x H&M, 2004
As the inaugural collaboration, no one could have expected that the 30-piece collection would sell out in just an hour. Even Lagerfeld was disappointed and was quoted at the time as saying: "This was supposed to last two weeks, and it’s over in 25 minutes. I’m sorry for the clients, because I like the idea that everyone could wear Lagerfeld."
The hottest ticket item? A $20 white t-shirt with an illustrated silhouette of the designer.
