The quirky style icon was spotted sporting a shockingly short grey style during Paris Fashion Week earlier this month (Mar13), covering up her new crop with a feather headdress.
However, she proudly displayed her shorn look during a protest against local authority spending cuts in Clapham, London on Wednesday (05Mar14).
Now a representative for the 72 year old explains she decided to ditch her long hair in support of climate change and to show she is proud of her age.
The spokesperson says, "Vivienne cut her hair as we must all wake up to climate change. And secondly she wanted to cut the red out for a while and have it white - to show she's proud of her age."
