Really, this is the best they could come with.
I have to reiterate what others have said, that it is very MaxMara, that maybe they don't have the budget anymore, but models against a plain backdrop is so unimaginative. I don't know who the current lensman is for the brand, but they have done wonderful campaigns in the past with Meisel and especially with Roversi and this is nowhere near those.
That said, campaigns I suppose, are all about showcasing the clothes and on that level it succeeds.
