I think the only high fashion brand that uses 'older' women as models is Lancome, who have Juliette Binoche and for a long time Isabella Rossellini.
Saying that it's normal for faces to change every so often, and Nicole has been the face of Chanel n.5 for quite a while now. I bet a lot of haters will use it to criticise her though. I wonder (and dread to think) if Lainey picked up that story.
