Dame Vivienne Westwood paid tribute to the Prince of Wales at Milan Fashion Week.
The fashion designer,73, honoured the 66-year-old royal by displaying a collection of notes praising his environmental work in the venue for her AW15 menswear show, reports the Daily Telegraph newspaper.
She wrote: ''I want to pay tribute to Prince Charles and the great job he's doing.
''We have adopted Prince Charles as patron of our collection.
''To sum up, if Prince Charles had ruled the world according to his priorities during the last 30 years, we would be alright and we would be tackling climate change''.
The fashion icon also paid homage to Prince Charles - who has worked to raise awareness of organic farming and climate change over the years - in her designs, combining Prince of Wales checks and houndstooth prints in her signature drop-crotch trousers, suits and belted coats.
Following the show, Vivienne was walked down the catwalk by her husband Andreas Kronthaler, sporting an oversized t-shirt with an enlarged image of Prince Charles' face.
The heir apparent wasn't the only royal to appear in the collection.
Vivienne also featured images of Queen Elizabeth II on bags and suits emblazoned with pound sterling bank notes.
It's time for a riot grrrl revolution.
