Diesel, renowned for its denim and casual wear, showcased a range of ultra-low-waist jeans and skirts, boucle jackets, and plastic-coated garments against a vivid backdrop of giant graffiti on the second day of the Milan Fashion Week.

In London during the fashion week prior, the likes of Rosie Huntington-Whiteley, Nicola Peltz, Brooklyn Beckham and Princess Diana 's nieces - aristocratic twins Lady Amelia and Lady Eliza Spencer, all put on stellar displays of glamour on the front row at shows including Burberry and Richard Quinn.
