How Diana first gave the leather look a leg-up - and cleared the way for a new generation of racy royals, as these pictures show...

We are used to seeing royal women in formal skirts, expensive gowns or, from time to time, even jeans. 

Yet even today, leather, is likely to raise an eyebrow or two.

It was Princess Diana who first led the way when she wore bright scarlet trousers for a theatre outing in 1987. 

Leather has slowly and stylishly been infiltrating royal wardrobes ever since...

A staple in Queen Letizia's wardrobe, these Hugo Boss trousers have been worn by her on three separate occasions.

Made from genuine leather, they incorporate a flattering high waist and a slim, cropped leg. 

The rich berry hue offers a welcome splash of colour, without being overly conspicuous.
