It's tempting to frantically find a fast-fashion version of whatever Meghan Markle or other royals are wearing—yes, we're guilty too—but emulating their style doesn't have to come at the expense of the environment. In honor of Earth Day, every single royal-inspired item I chose below boasts one or more sustainable elements (think recycled, renewable, and/or biodegradable materials, or reduced water usage and waste in the production cycle).

Another element of sustainability is working toward achieving a circular fashion system. The industry's current linear model is "take, make, dispose, [which results in] 73% of the world’s clothing eventually ending in landfills or being incinerated," per the Global Fashion Agenda, a Copenhagen-based nonprofit that aims to make sustainability fashionable and provide direction to industry leaders. Simple solutions to this massive problem include reselling or donating your clothes instead of disposing of them, and buying items made with recycled or repurposed materials.

Scroll down to shop outfits inspired by Meghan Markle, Queen Letizia, and Princess Charlene using brands committed to sustainability in their own unique ways.
