By

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.

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.

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.

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.
