The event created considerable excitement and Catherine's appearance captured the attention of the world. She wore an elegant black Alexander McQueen dress, which has become one of her most iconic looks. The dress was made from luxurious fabric and featured a classic calf-length design, adding a touch of sophistication. The dress featured a V-neckline and thick straps, giving the dress a look that was both modern and graceful. The fitted bodice flattered Catherine's figure and flowed into a beautiful, flowing skirt as she mingled with guests.

To accentuate her waist and add a touch of femininity, she paired the dress with a black leather belt that featured a delicate bow at the front. Her jewelry choices further elevated the look. She wore a matching ring, possibly by Balenciaga, although it was slightly different to her earrings. The earrings were Balenciaga pearl clips, originally introduced at the Trooping the Colour event in London. These elegant pearls were surrounded by glass diamonds and complemented a statement necklace with four large pearls on silver chains.

This necklace is similar to another piece Catherine wore at Trooping the Colour in June 2014, sparking interest among royal fashion fans about its provenance. Catherine then wore the stunning pearl necklace again to the Queen's Birthday celebrations on 17 July 2017 at the Orangery in Kensington Gardens. This highlights her penchant for repurposing treasured pieces from her wardrobe. Her accessories perfectly matched her look, including a pair of Jean V. Rossy First pumps in black suede.

The shoes featured a block heel, pointed toe, and ankle strap, balancing style and comfort. The outfit was completed with her favorite Cartier stainless steel watch, a sleek 33mm Balloon Bleu model that she wears for both formal and casual occasions. Katherine’s appearance in Paris was praised for her impeccable style, with her Alexander McQueen gown and delicate pearls making a lasting impression. Her thoughtful fashion choices reflected her down-to-earth nature while also cementing her status as a global fashion icon.

As anticipation grows for her return to the spotlight in late 2024 after chemotherapy, speculation about her outfit choices has grown, given her history of choosing meaningful pieces. Fans and critics alike are eager to see how her style evolves with her royal duties, showcasing strength, resilience and renewed energy. Katherine’s graceful legacy and easygoing charm promise to captivate audiences whenever she returns to the spotlight, making her return one of the most anticipated events of the year.
