17 Celebrity Style Moments That Made 2018 Unforgettable

The world waited with bated breath to see what the soon-to-be duchess would choose for her wedding to Prince Harry, and she did not disappoint. The former Suits actress made a major fashion statement in an ultrasimple and jaw-dropping bateau-neck, long-sleeve gown designed by Clare Waight Keller for Givenchy.

This year's Met Gala theme, "Heavenly Bodies: Fashion and the Catholic Imagination," was arguably the most dramatic ever. Celebrities like Katy Perry in dramatic wings and event cochair Rihanna in a papal-inspired ensemble by Margiela brought their A game.

The actress and screenwriter made sure her first Met Gala appearance did not go unnoticed. Waithe arrived in a Wes Gordon-designed rainbow cape, a nod to LGBTQ+ pride and a bold, poignant choice given the night's theme: "Heavenly Bodies: Fashion and the Catholic Imagination."

Her press tour wardrobe for A Simple Favor was full of pantsuits, but it was this neon-green Versace look that got everyone's attention. Lively is pretty fearless when it comes to fashion, and this traffic-stopping look made that fact abundantly clear.

Fresh off of Brandon Maxwell's Spring/Summer '19 runway, Gigi wore the designer's canary-yellow gown to the Business of Fashion 500 gala, but it was her bag — and its contents — that stole the show. The supermodel carried a clear handbag containing a bottle of Champagne and nothing else, and it was a whole dang mood.

Emma Thompson received the title of dame this year, but she made sure everyone knows she's still the same gal she's always been. The actress arrived at the Buckingham Palace investiture ceremony in a pantsuit and sneakers, because when you're Emma, you do what you want. Thompson's had a fraught history with heels, to be fair — she famously took off her Louboutins and threw them away at the Golden Globes in 2014, and she wore flats to the SAG Awards a few weeks later.

From her floral-adorned hair and bejeweled nails to her billowy floral Zac Posen gown, singer Andra Day brought the drama to this year's Oscars. She also brought her red carpet A game, treating us all to some refreshingly extra poses.

Not only did she make history at this year's Coachella as the festival's first black female headliner, but Beyoncé also set the bar seriously high when it came to performance wardrobes. She looked incredible both weekends in custom Balmain, changing five times over the course of her two-hour performances and paying homage to the queens who came before her, like Nefertiti.

Following the French Open announcement that her iconic black catsuit would be banned, Serena Williams clapped back by wearing not one but two Virgil Abloh-designed Off-White fishnet tutu ensembles while competing at the US Open: one in black and one in lavender.

Cardi confirmed she was pregnant during a performance on Saturday Night Live, appearing in a white formfitting Christian Siriano dress that showed off her baby bump. Her pregnancy was filled with dramatic looks, including an elaborate gem-encrusted Moschino by Jeremy Scott gown at the Met Gala.

Nicki Minaj isn't shy — and to prove it, she opted for a skin-baring ensemble by Virgil Abloh's streetwear brand Off-White at the 2018 MTV Video Music Awards. In a revealing beige bodysuit topped off with a sheer, ruffle-trim gown, the singer was impossible to miss.

After a season hiatus, Rihanna made her New York Fashion Week return with a bang. The presentation debuted her Savage X Fenty lingerie collection, but it was so much more than that. The show was an inclusive, diverse, sexy celebration of women that included curvy and pregnant models, women of all races, and theatrical choreography. We've come to expect nothing less from the singer and style mogul.

There's a reason Lady Gaga is, well, Lady Gaga. For the UK premiere of her buzzworthy film, she chose an Alexander McQueen creation that was truly fit for a queen. The Victorian-inspired ensemble was stitched with pearls and feathers and covered in gold accents, and it came complete with a regal ruffled collar.

The Black-ish star was a vision in fuchsia at the Emmys this year, taking to the red carpet in a voluminous Valentino Haute Couture gown that very few people could pull off. From the billowy sleeves to the very full skirt, this pink confection had us all gasping.

The meaning behind Tiffany Haddish's Emmys gown, designed by Prabal Gurung, was actually quite touching. The actress asked the designer to create a dress that paid tribute to her late father's native country, Eritrea, and he did just that, using the colors of the nation's flag.

At the 2018 E! People's Choice Awards, Kim had our eyes playing tricks on us in a vintage Jean Paul Gaultier dress from What Goes Around Comes Around. The skintight sheer dress was covered in clashing horizontal and vertical lines and was impossible to look away from.

In a celebration that lasted several days and included several stunning looks, Priyanka Chopra married Nick Jonas, giving us eye candy to feast on for months. From her bright embellished sherwani (for their mehendi ceremony) to her silver and gold sari (for their sangeet) to both her wedding ceremony looks (an ornate Sabyasachi red lehenga and a white hand-beaded and hand-embroidered Ralph Lauren dress with a dramatic veil), we're going to need a nap to recover.
