Nothing yet from German Vogue, but I get the feeling their putting something special together. Him being just about the most famous designer of German origin, next to Jim Sander.
I'm sure Babeth will also do a tribute. She ran a limited digital cover of him for the March or April issue, but that's it. A lot of magazines may still be working on their tributes, and for me that's fine. Rather take the time, see what everyone else did, and do something unique than just rushing to get it over with.
There may be tributes in other magazines too. I've only posted what I have access to.
