Princess Mary is the definition of chic simplicity at a conference in New Delhi with Prince Frederik

Crown Princess Mary is known for her sensational style.

And the Danish royal, 51, once again displayed her impeccable taste at the India-Denmark: Partners for Green and Sustainable Progress conference in New Delhi on Tuesday.

Mary looked glammed up for the occasion in a tailored black top and pants.

She completed her look with a colorful coat that featured abstract designs and a crimson lapel.

Opting to wear her brown locks straight to the event, Mary donned a subtle makeup palette to match her style status.

Elsewhere, her husband Prince Frederik looked dapper in a classic blue suit as he sat next to Danish Foreign Minister Lars Løkke Rasmussen.

Known for her eye for style, the soon-to-be Queen of Denmark regularly mixes haute couture with budget pieces and champions locally made clothing whenever she can.

So keen is Mary’s eye for fashion that a public vote twice named her the world’s most stylish royal, ahead of the Duchess of Cambridge, Queen Letizia of Spain and Queen Rania of Jordan.

The late Chanel designer Karl Lagerfeld once described Mary and Kate Middleton as “real sisters” thanks to their strikingly similar looks and similar taste in clothes.

The future queen of Denmark has posed for Vogue Australia and Vogue Germany and is a patron of Global Fashion Agenda, which oversees the annual Copenhagen Fashion Summit.

The love story between Princess Mary and Prince Frederick is well documented.

HRH Crown Princess Mary was “just” Mary, a marketing manager at an advertising company, when she met Crown Prince Frederik in a pub in Sydney during the 2000 Sydney Olympics.

On May 14, 2004, Mary married her Prince in a lavish ceremony attended by royalty and the world’s media at Copenhagen Cathedral in the Danish capital.

It was described as the last happy fairy tale ending with the prince marrying the beautiful commoner.

The guest list included the kings and queens of Sweden, Norway, Spain, Belgium and the Netherlands including Prince Edward, Earl of Wessex and Sofia, Countess of Wessex.

The Crown Prince couple are parents to Prince Christian, Princess Isabella and twins, Prince Vincent and Princess Josephine.
