No doubt working for Vogue has put her in a bubble.
From the start being a Von Thurn Und Taxis would have put her in a bubble but any efforts by friends and family to stop her from having a rich girl's careless flippancy was eroded when she joined Vogue.
I always thought she wrote better when she was with Finch's Quarterly and lived (by her standards) a quieter life. At Finch's Quarterly she wrote from the heart about her family & her life in London and came across well. In contrast the vogue articles seem to have attracted a lot of criticism for their tendency to be just articles of name dropping, label dropping and globetrotting.
I was always amazed that she had a public twitter & instagram but being a member of the Vogue crowd obviously meant selling herself to the world. All her life she must have seen Gloria dip in and out the New York/Paris social scene, friends with Warhol, Bianca Jagger and Andre Talley etc - and want that sort of recognition as a fashion icon/celebrity for herself- a piece of that life.
I think deep down she is just as good hearted as her brother and sister but she has been weaker than them in her lifestyle choices. Maria paints to please herself-Elisabeth writes to please Vogue. Albert spends about 8 weekends a year racing - Elisabeth probably spends only about 8 weekends a year not living in pursuit of frivolity. The people who she mixes with love her when she is outrageous, wildly dressed and wearing fur/fox hunting - does she need the Harry Brants of this world? Does she need to be always planning the next outfit?
She never seems to stay in place more than a week at a time (perhaps there is some income tax advantage to this?). She has no husband or children to come home to (nor does it look at the moment like she ever will). She spends a great deal of money (even after freebies) on her image. If she wishes to be a real writer then she needs to quit Vogue and write like she did in the Finch Quarterly days.
