Avocados: good for eating, Instagramming, and bankrupting aspiring homeowners. Or at least that’s usually the case. As it turns out, the avocado might qualify as a super food not just for its nutritional qualities, but for its potential to upgrade your wardrobe.

That’s because it turns out that the parts of an avocado that we usually regard as useless (or even potentially injurious) are actually quite useful as the basic components of a DIY fabric dye. And best of all, the process somehow leaves garments looking like a muted shade of millennial pink.

According to self-taught botanical dye expert Rebecca Desnos, it’s a perfectly simple at-home process with little to no culinary or sartorial knowledge required. First, hoard some finished avocados and some white fabric you’re ready to jazz up. Scrub all of the green avocado flesh from the skins and pints, since they form the basis of the dye. Ideally you’ll want to use roughly three or four fresh skins and stones for a decently vibrant color, but storing and freezing works just as well.

From there, it’s kind of like making a soup, but with clothes. Just gently heat a pot of water with your avocado offal for a while. Once you like the shade you see in there, it’s time to dump out the avocado ingredients and swap in your fabric of choice, letting it steep for a while so the color can truly soak in. In essence, the longer you let the avocado steep the more millennial pink the pigment. But given that every avocado is different (and the characteristics of your tapwater factor in as well), you’ll have to keep a close eye on how things are progressing.

So there you have it. Probably not a perfect system, but doing some at-home clothes dyeing seems like a solid way to squeeze some extra value out of your pricey avocados. There’s a case to be made that both millennial pink and the avocado itself are two things we should’ve left behind in 2017, but this sustainable approach to fashion isn’t going out of style anytime soon.
