Tess Holliday Stars In H&M's Sustainable Fashion Campaign

Bringing #effyourbeautystandards to the mainstream.

Tess Holliday is hitting the mainstream market, and we couldn't be happier.

Fresh off of her Addition Elle fall campaign, the 20-year-old model now stars in H&M's sustainable fashion commercial alongside Iggy Pop, Daniel Lismore and Karley Sciortino.

The "Close the Loop" program encourages consumers to recycle their clothes at the Swedish retailer's stores to be reused in H&M's Conscious Collection.

Tess, who is the first model of her size and height (size 22, 5'5) to be signed to a major agency, shared a photo of herself in the campaign on Instagram, in which she wears a red, buttoned-up blazer and pink pants.

"😭❤️💋🌹🍒 #HMConscious #HMClosetheLoop #tessholliday 🎈🎈🎈," the mother-of-one captioned the snap, adding, "(p.s. If you don't like the outfit, cool but this is a major moment for me & I'M happy ✌🏻)."

She later shared a heartfelt post on the social media network, captioning the photo: "I've watched the H&M campaign a million times & cried. To have the chance to part of something so diverse means more than I can express. Then I shot with an amazing team at @modestories & came home to cupcakes from my friends at @cupcakeroyale! Today, I'm celebrating!!🎉 💙💚💛💜💖 #tessholliday #gratefulasfuck #effyourbeautystandards (Dress is by @chubbycartwheels & currently out of stock but check her out anyways✌🏼️)."
