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.

Amal Clooney

The stylish barrister and her husband, George, attended Meghan Markle and Prince Harry's summer nuptials, and her style was on-point.

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 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.
