True confessions: I’m secretly a total Harry Potter nerd. Okay, maybe it’s not so secret… (#TeamHufflepuff anyone?) Which is why I did a literal happy dance in my living room when I saw Emma Watson’s gown for last night’s Met Gala.

Her look, designed by Calvin Klein with help from Eco-Age, incorporated recycled plastics into the body of the gown.  “Plastic is one of the biggest pollutants on the planet,” said Watson on Facebook. “Being able to repurpose this waste and incorporate it into my gown for the #MetGala proves the power that creativity, technology and fashion can have by working together.”

Emma’s point about the power of creativity is an important reminder. There are a lot of problems—big problems—facing our planet, and it’s going to require ingenuity and innovation to solve them. And if finding a sustainable way to create red carpet fashion brings more people to the table, then I say, “The more the merrier!”
