^Exactly, Givenchy seem to be putting an increased focus on the Lucrezia bag this season especially, so the circulation of Kate's image is going to be more popular, I think it's also a clever strategy for the bag to be photographed with Kate.

Kate's shot is being circulated more because the emphasis is on the bag and as you know accessories=$$$.
However, Kate's image isn't used for the GIVENCHY catalog, only MCB & BABY was made into a huge poster. Every year one image only is selected as a GIVENCHY poster/lookbook... Sadly for me who collects Kate, it was not Kate.
