While discussions on sustainability can hardly be had around an event like the Met Gala, what with its monumental scale, this year, some sparks of a sustainable effort at couture and custom fashion were noted on the red carpet. From rewearing clothes (including a wedding dress) to new, upcycled custom ensembles, these stars made a statement on sustainable fashion at the 2022 Met Gala.

It might be a far stretch to say that Kim K had sustainability on her mind when she wore the dress Marilyn Monroe wore back in 1962 when she sang 'Happy Birthday' to President JFK, but the fact that she donned a vintage dress certainly counts. Emma Stone rewore her Louis Vuitton wedding dress from when she married David McCary in 2020. While we love a rewear moment, the dress, however, fell flat on the Met Gala red carpet and did not adhere to the evening's theme by any stretch. 📣 For more lifestyle news, follow us on Instagram | Twitter | Facebook and don't miss out on the latest updates!
