Despite being an 86-year-old, Her Majesty is a "bona fide style queen", says Minogue.

Speaking to Glamour magazine, the singer and fashionista said that the Queen has dodged "fuddy-duddy land" and gets her fashion choices just right. 

"A grandmother several times over, the queen could be forgiven for sauntering into fuddy-duddy land, but instead, she dresses age-appropriately, sticking to colour-blocking suits she knows, and getting it so right. Look no further than the primrose dress she wore to Catherine and William's wedding, and the series of acid-brights she wore for last year's tour of Australia. There aren't lots of octogenarian fashion icons, but this 86 year old is a bona fide style queen."

She concluded: "Her wardrobe is a triumph of stylish functionality. When she stepped off the plane in Australia last October, she spent most of her 11-day tour walking around, meeting her subjects. Her courtiers must think through every single element of her attire."
