Chav like behaviour

Help Please!!!!! My girlfriend recently came home with a Burberry scarf, I’m a little concerned about this as it appears to be chav like behaviour, particularly as it would appear that this is fake burberry!!!! Also a face Gucci bag has turned up…. What course of action should I take, I’m a little traumatised by the whole thing, should I buy her little lights for the washer jets of her Clio for Christmas…..
