Mary Portas's hair.

[Hellishday]

I have (on 2 MNetters recommendation) booked a hair appointment with a new salon next week.
I have hair longer than Mary's, in a choppy bob, which quite frankly, needs an update.
I do love her bob, but not sure how short it is at the back...I do not want it cut halfway up my head. Has anyone seen any photos of her from the back?
I am 6 feet tall, slim, 51.
In fact I am Mary

Corinne Drewery. Google. Also Vidal Sassoon. Bob worship webpage for inspiration. Mary style needs a tweek IMO.
