Emma Watson and Scarlett Johansson were among the glamorous arrivals as they headed to a swanky Prada dinner at Milan Fashion Week on Thursday.

The Harry Potter star, 33, put on a leggy display in a plunging white mini dress as she joined the actress, 38, and online star Charli D'Amelio for the swanky event.

After opting for a chic LBD at the fashion show earlier in the day, Emma changed into the eye-catching mini dress with matching heels for the evening.

Finishing her look with a Noughties-inspired handbag, Emma blew a kiss for her delighted fans as she headed into the dinner.

Meanwhile, Scarlett opted for a more pared-back ensemble as she wrapped up in an oversized black jacket.

The Avengers star teamed her look with chunky black loafers and long black lace skirt as she made her solo arrival. 

Charli D'Amelio flashed a glimpse of her abs in a black bralet and an oversized camel blazer, teamed with a revealing white mini skirt.

Italian blogger Chiara Ferragni donned a similarly revealing look with a navy blue miniskirt and an oversized black blazer.

Top Boy star Letitia Wright opted for an eye-catching black cropped buttoned blouse and matching trousers as she arrived for the swanky occasion.

The actress opted for chunky black loafers as she posed for selfies with delighted fans outside the dinner.

Earlier in the day, a slew of big names took their place on the front row for the Prada Fashion Show.

Scarlett Johansson, Emma Watson and Sofia Richie were among the early high-profile arrivals outside Fondazione Prada as the celebrated fashion house presented its womenswear spring-summer 2024 range. 

Making her way inside, Hollywood star Scarlett turned heads in an elegant cross-strap dress from the high-end brand, cinched with a black leather belt. 

She completed the look with distinctively shaped heels, while cloudy weather didn't deter her from wearing heavily tinted sunglasses. 

Opting for a stylish black halter neck minidress - Prada's take on the classic LBD - Emma caught the eye as she greeted onlookers ahead of the first look presentation. 

Black stiletto heels continued a subdued colour scheme, while a simple leather handbag served as her only notable accessory. 

The Harry Potter star drew further attention to her delicately proportioned features by opting for deft touches of make-up, selected from a natural colour palette.

Meanwhile Sofia, 25, deviated from classic black, opting instead for a smart red roll neck and elegant Prada pencil trousers. 

The adopted daughter of Motown legend Lionel Richie completed the look with a sophisticated plaid coat, while black heels continued a recurring trend among guests at the exclusive event. 

Other guests on the day included British actor Benedict Cumberbatch,  whose floral patterned shirt and sweeping cream Prada coat ensured he claimed his own share of the spotlight. 

Elsewhere French actor Vincent Cassel, Spanish singer Rosalia and American actress Diana Silvers were also seen making their way inside ahead of Thursday's show. 

Milan kicked off its catwalk calendar on Wednesday, with Italian luxury label Fendi exploring the "ease of dressing with a certain Roman freeedom" at its womenswear fashion show.

Milan Fashion Week follows New York and London events in which designers have been presenting their creations for spring/summer 2024, and includes 62 physical fashion shows.

It runs until September 25 and will feature shows from high-end labels including Giorgio Armani, Prada, Dolce & Gabbana and Versace.

Milan Fashion Week will mark the debut of Sabato De Sarno as creative director of Gucci, Peter Hawkings as creative director of Tom Ford, and Simone Bellotti as creative director of Bally.
