Dating Comme des Garcons

With Comme des Garçons some items are easy to date, others have no information to be able to properly date them. Most items have a date on the wash label with the letters "AD" before it. 

Sometimes some items from Spring Summer of a specific year have the previous year on the label.

If you want to be more specific than just the year, it's best to look for fashion shows and lookbooks as references.
