Does anyone know a way to find out the reference number on past items (that aren't on the website)?
Do you mean reference numbers for Eluxury, Ebay, or the Dior site?
the Dior site
Hmmm...I didn't even know that the Dior site had reference numbers for their items. Does anyone else know?
Yes, Dior has reference numbers on their site if you go to product search. And if you want the past season's ref number, you can get them on the catalogues I think. I had one in for spring but don't know where it is now.
