Take a look back on this year's show-stopping fashion moments from Rihanna's Met Gala ensemble to Lady Gaga's feathered gown.
2018's fashion did not disappoint.
Hollywood's biggest stars served up major sartorial moments on the red carpet, at weddings and beyond with a bevy of thrilling styles from daring choices to simply gorgeous ensembles.
Reflect back on this year's most memorable looks -- and the celebs who flawlessly rocked them -- including Rihanna, Amal Clooney, Meghan Markle, Kendall Jenner and more.
Cardi B
Kicking off the list is the rapper in a structured custom dress by Ashi Studio at the GRAMMYs. 2018 was undoubtedly Cardi's year, and she owned it in this stunning ivory lace number, complete with diamond cuffs and a romantic updo.
Lupita Nyong'o
The Black Panther star was a Wakandan goddess in a regal violet pleated gown adorned with gold bodice armor, custom designed by Versace, at the film's Los Angeles premiere.
Dakota Johnson
The actress brought sparkle to the empowering all-black dress code in solidarity with the Time's Up Now movement at the Golden Globe Awards in a velvet Gucci gown with starry embellished back.
Saoirse Ronan
The three-time Academy Award nominee instantly gave us modern Marilyn Monroe in Gentlemen Prefer Blondes vibes at the Oscars in an utterly chic, pink bespoke Calvin Klein bowed creation. Her sleek bob, drop earrings and matching pointed-toe pumps complemented this sheer perfect ensemble.
Rihanna
The pop star always turns out a jaw-dropping outfit for the Met Gala, and this year, she continued to up the ante. Dressed for the "Heavenly Bodies: Fashion and the Catholic Imagination" theme, RiRi rocked a jewel-encrusted mini dress, robe and papal hat by Maison Margiela.
Kendall Jenner
The supermodel is never shy when it comes to the naked dress, and she delivered just that in haute couture at the Cannes Film Festival via a cinched, plunging sheer tulle tiered Schiaparelli gown and beautiful emerald jewelry from Chopard.
Amal Clooney
The stylish barrister and her husband, George, attended Meghan Markle and Prince Harry's summer nuptials, and her style was on-point. Clooney was every bit as elegant in a honey yellow midi dress and matching hat. It garnered so much attention that designer Stella McCartney recently released the dress for sale.
Meghan Markle
Of course, we can't talk about the royal wedding without looking back on the multiple looks of the bride herself. The former Suits actress became the Duchess of Sussex when she married Prince Harry in May. The new royal took our breath away in her now iconic custom bateau neckline Givenchy wedding dress for the ceremony and changed into a bespoke halter gown by Stella McCartney for the reception.
Janelle Monae
The musician celebrated Pride Month on the red carpet at the BET Awards in a striking rainbow gown by Nicolas Jebran, conductor hat and crystal-embellished bag.
Constance Wu
The Crazy Rich Asians leading lady stuck to the film's extravagant theme for its Los Angeles premiere, wearing a Ralph & Russo haute couture gown. The show-stopping metallic silver dress, with structured bust and tasseled off-the-shoulder straps, featured 200,000 crystals, worn with 90 carats of diamonds of Lorraine Schwartz jewelry.
Lady Gaga
The multitalented artist started the A Star Is Born press tour with a bang in a voluminous light pink feathered gown from Valentino's haute couture collection. Gaga floated on the red carpet alongside co-star Bradley Cooper at the Venice Film Festival.
Zendaya
The actress was a complete knockout in a purple-and-yellow satin couture gown with crystal chainmail bodice by Ralph & Russo, finished off with slicked back hair and sultry, smokey eyes at the GQ Men of the Year Awards.
Bella Hadid
The bombshell proved her bod won't quit in a form-fitting, sheer, nude-colored custom corseted Mugler bodysuit, Lorraine Schwartz jewelry and lucite pumps at the Harper's Bazaar Icons Party during New York Fashion Week.
Tracee Ellis Ross
The Blackish actress loves to take risks on the red carpet and she pumped up the volume in a pillowy fuchsia taffeta gown from Valentino's haute couture line at the Emmys, complete with matching lip and orange eyeshadow.
Taylor Swift
The wait was worth it! The songstress returned to the red carpet at the American Music Awards in a disco ball-inspired long-sleeve mini dress and coordinating thigh-high boots by Balmain.
Cara Delevingne
The model-turned-actress' borrowed-from-the-boys ensemble broke royal protocol in the chicest way at Princess Eugenie's wedding this fall. The British beauty was dapper all the way in a black tailored Emporio Armani trouser suit with cummerbund and coattail, worn with a tie, stiletto pumps and a top hat.
Amber Heard
The Aquaman actress made a huge splash at the film's London premiere in a decadent green-and-gold cut-out couture gown and swim cap by Valentino. We love the blonde's commitment to thematic dressing.
Emily Blunt
The Mary Poppins Returns star was a fairy tale dream in a plunging white gown with balloon sleeves by Yanina Couture at the film's Los Angeles premiere.
Priyanka Chopra
The nuptials of Nick Jonas and the Quantico actress was the second biggest celeb wedding of the year, following the Duke and Duchess of Sussex's. Celebrations spanned over multiple days, which included five outfit changes. Chopra and Jonas both participated in an Indian and Christian ceremony, and her dresses for both were equally incredible. She first wore a beaded, high-neck buttoned white wedding dress, custom designed by Ralph Lauren, finished off with a 75-foot-long tulle veil. For the Hindu ceremony, she chose a red crystal-embroidered traditional lehenga ensemble by Sabyasachi Mukherjee.
Jennifer Lopez
Volume was the name of the game this year! J.Lo donned the trend via a dramatic hot pink tulle dress with lengthy train by Giambattista Valli at the New York City premiere of Second Act, alongside boyfriend Alex Rodriguez.
