Olivia Wilde just launched an eco-friendly tee collection and Jonathan Van Ness is obsessed

Olivia Wilde's eco-friendly tees just got the "Queer Eye" stamp of approval.

The actress just launched her #ChooseUsed capsule collection on thredUP, and noted fashion maven Jonathan Van Ness is loving the design -- and the greater cause.

"Giving clothes a second chance to go on the dance floor is a gorgeous way to help our planet," Van Ness wrote on Instagram. "Especially those lil bb walruses."

The colorful but classic tees and sweatshirts come from J. Crew, Victoria's Secret, Michael Kors and more major labels. Each unique top is emblazoned with phrases like "I Wear Used Clothes" and "Used Goods." (Van Ness chose a pink cropped hoodie.)

Also on board with the release are Lena Dunham and Sophia Bush, both of whom also showed off their new tops. Dunham snagged a white tee while Bush opted for a gray sweatshirt.

A portion of proceeds benefit thredUP's sustainable fashion initiative, which means this is one online purchase you can actually feel good about -- and just in time for Earth Day.
