A decade has passed since Karl Lagerfeld did a one-off collaboration for H&M — and the fashion industry has never been the same. “Inexpensive is not ‘cheap’ anymore, that’s why the luxury industry has to make an even bigger effort. I think all that is very healthy,” Lagerfeld muses in “The First Ten Years,” a commemorative book H&M is releasing November 6th  in tandem with its latest holiday tie-up, Alexander Wang for H&M.

Available in about 250 stores, it’s priced at $11.50 with 25 percent of proceeds going to UNICEF.

H&M dug out unseen imagery and solicited contributions from each of its participating designers, including Donatella Versace, Alber Elbaz and Roberto Cavalli. The Swedish retailer has also mounting a retrospective exhibition of its annual collaborations at its Fifth Avenue flagship in New York.

Said Lagerfeld: “I never expected it to make such a splash.”
