Shopping for sustainable fashion shouldn't require a PhD. With hundreds of eco-labels out there, how do you know what's real and what's greenwashing?
Since there's no official rulebook for sustainability claims, independent certifications fill the gap. Think of them as report cards—some grade materials, others worker treatment, and some cover the whole supply chain. Here's what the main ones actually mean.

What This Means for You
No single certification covers everything. Focus on what matters to you—organic materials, worker welfare, recycled content, or animal rights—and look for those specific labels.
Certifications aren't perfect, but they provide third-party verification instead of just taking brands at their word. That's worth something.
