Kidman, who is co-chairing the 2026 event and is attending with her daughter Sunday Rose, wore a red sequin gown with a red feather detail around her waist.
Sunday Rose wore a fun, pink textured dress with purple flower details, while American model Graham posed in a beige-coloured flowing gown.
British model and actress Delevingne posed for photographs in a sheer figure-hugging dark-coloured dress.
The annual gala on Monday evening, US time, is attended by stars from across music, film, TV and fashion, raising money for the Metropolitan Museum of Art and celebrating the opening of the Costume Institute's spring exhibition at the New York museum.
Vogue red carpet correspondent Emma Chamberlain and professional tennis player Naomi Osaka did not play it safe this year, delivering custom works of art in honour of the dress code "Fashion is art".
Osaka stunned as she left The Mark Hotel for the Gala in a dramatic Robert Wun white sculptural gown fitted with exaggerated shoulders and adorned with red feathers and a matching headpiece.
A similar look by Wun sits inside the Metropolitan Museum of Art's Costume Institute exhibit, Costume Art.
Chamberlain, who is known to change looks throughout the night, arrived in a breathtaking Mugler by Miguel Castro Freitas hand-painted dress.
The star was dipped in a rainbow of colours from her decolletage down to the train of her body-hugging dress with fringe falling down the cuffs of the long-sleeve gown.
With all the fanfare around The Devil Wears Prada 2, Met Gala co-chair Anna Wintour opted for a cool mint ensemble - not the trendy cerulean blue from the first film.
Wintour's look featured a feathered cape and a beaded dress by Matthieu Blazy for Chanel that she classically paired with her signature bob and oversized sunglasses.
Fellow co-chair Venus Williams chose a more subdued look. Williams wore a sparkling black off-the-shoulder gown with a dazzling bejewelled neckpiece in homage to a painting of herself done by Robert Pruitt.
Event sponsor Lauren Sanchez Bezos arrived in a form-fitting Schiaparelli gown.
Unlike the 2025 blue carpet, this year's carpet appeared intentionally forgotten by time with grass creeping up the steps.
The carpet featured patches of overgrown grass peeking out from the stone steps with manicured shrubs lining the side railing and white wisteria dangling from the roof.
