Is Princess Polly sustainable? We checked 12,043 products.

On fabric composition — the one factor we can measure — Princess Polly averages 34.1% natural fibre across 12,043 products, ranking #47 of 55 brands we track. That's toward the bottom. Fabric data can't speak to labor practices, emissions, or water use, so treat this as one input, not a verdict.

We measure fabric, not business models — so we can't classify Princess Polly as fast fashion or not. What the data shows: 50.3% of their products are polyester-heavy and 24.4% are nearly all-natural (95%+ natural fibre). Heavy synthetic reliance often correlates with fast-fashion production, but it isn't proof either way.

Fabric composition is a reasonable quality proxy: natural fibres generally breathe better, last longer, and shed fewer microplastics. Princess Polly averages 34.1% natural fibre, which is below average. Individual items vary widely, so check the composition label on each piece.

That depends on what you're buying. 24.4% of Princess Polly's catalog is nearly all-natural, so good pieces exist even though the average leans synthetic. Use the Fibr extension to check fabric composition on individual items while you shop — it varies more within a brand than between brands.

65.7% of Princess Polly products are majority synthetic (less than 50% natural fibre by weighted content). The catalog as a whole averages 34.1% natural fibre, so it leans synthetic.
