Princess Kate Middleton simply looked ravishing in this one of a kind monochrome dress.
The Duchess of Cambridge is currently on a Royal visit in India, alongside her husband Prince William .
During early celebrations for the Queen’s birthday in New Delhi, she shared the reasons behind her trim waistline with a party guest.
Kate was asked by Professor Bulbul Dhar-James how she stays looking so trim.
Prof Dhar-James said: “We said ‘how do you lose all the weight after having two kids?’
“And she said, ‘I am running after my kids.”
