Specifically hot pink was a clear favourite, seen on everyone from Justin Bieber, who added a pop of colour to his grey oversized Balenciaga suit with a magenta beanie hat, to Travis Barker, who was seen in a fuchsia Givenchy overcoat.
Valentino was behind a handful of the vibrant looks, including Porter's own ensemble and one of two looks from Saweetie. The rapper wore a pink gown with matching gloves by the fashion house to arrive at the awards ceremony, and then changed into a black Oscar de la Renta gown for a second trip down the red carpet.
The pink-out will come as no surprise to fashion watchers, who will have seen the Valentino presentation at Paris Fashion Week in March. Not only did models walk in head-to-toe pink looks, the catwalk itself was also in the colour.
The fashion house has taken such ownership of the specific shade of pink that Pink PP, named after the brand's creative director Pierpaolo Piccioli, will be a Pantone colour. It has drawn comparisons with Valentino red, a historic favourite of the fashion house, favoured by founder Valentino Garavani.
“I always want pink in my collections. It’s a colour I feel you can subvert better, because it already has a lot of meaning. It changed [over] the centuries: it was the colour of the power of men, then it became girlish … I like to subvert the idea. Today, it means different things,” Piccioli said when presenting his autumn/winter 2022 collection.
Bringing it down a notch from hot pink, Chrissy Teigen wore a vibrant Nicole + Felicia gown, while a similar shade was seen on St Vincent, who wore a 1970s-style gown with ruffled sleeves.
Baby pink was also on the sartorial menu. Grammys host Trevor Noah wore a pastel tuxedo, while American singer Tinashe wore a latex design by GCDS.
