Met Gala 2018: Best-dressed guests on the red carpet, from Rihanna to Katy Perry

Some celebrities stunned while others blended into the background

The annual Met Gala is one of the biggest fashion events of the year, and this year’s outfits did not disappoint.

Incorporating the theme Heavenly Bodies: Fashion and the Catholic Imagination, the event's most controversial theme to date, the A-list used this year’s red carpet to show off their most sacred looks.

With crowns, crosses, and wings, the 2018 Met Gala red carpet was full of over-the-top ensembles that combined high-fashion and religion.

These are the best and worst-dressed from the 2018 Met Gala.

The best:

For many of the A-listers, a spot on the best-dressed list required some commitment to the theme. These included Jennifer Lopez, who sparkled in Balmain and flirted with boyfriend Alex Rodriguez, Rihanna, who took papal-chic to a whole new level, and Katy Perry, whose extravagant angel wings only added to the appeal of her ensemble.

SZA stood out in a pale-pink gown with a gold bodice, and a heavenly-inspired gold halo, as did Kim Kardashian West in a Versace gold-sequined gown adorned with crosses and Gigi Hadid in Versace.

Also on the best-dressed list were Ariana Grande in Vera Wang, Amber Heard, who turned heads in a stunning red gown, and Priyanka Chopra in a Ralph Lauren red velvet dress and gold chain-mail headdress.

But, as with any red carpet, there are some ensembles that just don't come together.

At the Met Gala, the fashion stakes are especially high - and this year, some celebrities fell flat.

The worst:

This year's worst-dressed were mostly those who didn't incorporate the heavenly theme into their outfits - or did so to disastrous outcomes.

Kylie Jenner left viewers unimpressed with her secular ensemble, opting for a simple black gown and sunglasses indoors. Sister Kendall Jenner made the list as well.

Sarah Jessica Parker's Dolce & Gabbana ensemble captured attention, but not necessarily for the right reasons. Featuring an over-the-top gold headpiece and equally busy dress, the usually-fashionable actress's outfit was a lot to take in.

Scarlett Johansson looked beautiful, but her outfit was forgettable, as it had nothing to do with the theme. The same was true for Miley Cyrus, whose daring low-cut satin gown would have been better suited for a different red carpet.

And Amal Clooney's outfit of flowers paired with pants by Richard Quin was gorgeous - but the co-host of the event didn't bring the dazzle that one expects from outfits at the Met Gala.

Overall, this year's Met Gala, filled with extravagant headpieces and lots of gold, was one to remember.

As exhibition curator Andrew Bolton said of the theme: "Dress is central to any discussion about religion."
