That's hot. Paris Hilton was living her best life at Sofia Richie's wedding on 22 April, wearing a long-sleeve turquoise gown by Jenny Packham and solidifying her spot on the best-dressed list. Styled by Sammy K., the 42-year-old mogul sparkled in a mermaid silhouette complete with sequin mesh, a gathered waist, and a deep plunging neckline embellished with tiny silver crystals. Adding even more glamour, Hilton accessorised the look with a Jean Dousset diamond choker and stud earrings, as well as a shimmery silver clutch by Tyler Ellis and pointed-toe heels.

"Fairytales do come true," she captioned her Instagram post, sharing more photos from the day. "What a magical wedding weekend." And to her credit, her dress did look like something out of a storybook, with whimsical details reminiscent of the mermaid-core trend. The seafoam colour and shimmery material only added to the fantasy.

Hilton's dreamy look was fitting for what may have been one of the most fashionable weddings of the year. Richie married Elliot Grainge in three custom Chanel wedding dresses, each one highlighting a different side of her timeless style. Later in the night, Hilton also changed into another gown, this time navy blue with a crystallised cape, to celebrate with Richie at her afterparty. Read on to see how Hilton put her own ethereal spin on traditional wedding guest attire.
