The singer, who was made the face of Gucci Tailoring in June 2018, has become known for his unabashedly bold style of dressing, frequently donning bright colours and eye-catching patterns.
In the new campaign for Gucci's pre-Autumn 2019 men's tailoring collection, Styles wears a variety of striking suits in order to showcase Italian fashion house's "vision for a new formal wardrobe".
The campaign was photographed by American film director Harmony Korine.
Korine also shot Gucci's pre-Autumn 2019 collection, which was unveiled in December last year.
In one of the pictures of Styles, the musician stands behind a desk with a phone to his ear, wearing a red bandana on his head, a burgundy jacket with a fuchsia lapel, a striped shirt and blush pink trousers.
Two ancient Roman-esque busts are included in the composition, in addition to a piglet standing on the desk and a swan behind Styles' head.
In another picture taken by Korine for the campaign, Styles wears the same bandana with a royal blue, velvet suit, a swan perched on his right hand.
Gucci creative director Alessandro Michele aspired to use the campaign to provide a "new take on formalwear, challenging today's norms in men's suiting".
"Accompanied as in the past by a gang of animals – this time piglets and swans – Styles plays an eccentric yet nonchalant character, surrounded by his pets in a classical environment, reflecting the House's vision for a new formal wardrobe."
Earlier this month, Styles attended the annual Met Gala wearing a bespoke, gothic, "Camp"-inspired ensemble designed by Gucci.
His look included a sheer frilled black blouse, black trousers, black heeled boots and a single pearl earring.
