How about a book about Alexander McQueen, such as "Alexander McQueen: Savage Beauty" or "Alexander McQueen: Unseen"? Another idea could be a custom-made t-shirt or hoodie with an Alexander McQueen design, or a limited edition piece from one of McQueen's past collections (you may be able to find these on resale sites such as Grailed or Depop). You could also consider gifting a pair of Alexander McQueen sneakers or a leather backpack from the brand's current collection, if your budget allows for it.
Or you can get him a star map with an important date you share.
