Bershka is one of the biggest fast fashion retailers in the world — and with 9,339 products in Fibr’s database, it’s the largest dataset we’ve ever analysed. So what’s it all actually made of?
We parsed every fabric label. Here’s what the data says.
Overview
At 62.7% average natural fibre, Bershka sits above the fast fashion average. Nearly half its products are entirely natural. But one in four is still majority polyester — the split depends almost entirely on what category you’re shopping.
What’s Bershka Made Of?
These are the five most common fibres across all 9,339 Bershka products, measured by the percentage of products that contain each fibre.
Cotton is the most common fibre at Bershka, appearing in nearly half of all products. But polyester isn’t far behind at 38.1%. Elastane shows up at a similar rate — usually in small percentages for stretch, which is expected in modern clothing.
Natural Fibre Distribution
Averages can mislead. Here’s how Bershka’s 9,339 products actually distribute across natural fibre brackets.
The distribution is bimodal. Over half of Bershka’s products are 75%+ natural fibre — mostly cotton basics. But 27.9% sit in the 0–25% bracket, meaning they’re overwhelmingly synthetic. There’s very little middle ground.
Category Breakdown
This is where the real story is. Bershka’s average hides massive variation between categories.
| # | Category | Avg Natural Fibre | Products |
|---|---|---|---|
| 1 | Jeans | 98.7% | 1,015 |
| 2 | T-shirts | 87.1% | 1,021 |
| 3 | Shirts | 81.4% | 705 |
| 4 | Shorts | 77.1% | 210 |
| 5 | Pants | 61.8% | 1,279 |
| 6 | Skirts | 56.7% | 503 |
| 7 | Jackets | 56.6% | 534 |
| 8 | Blazers | 55.8% | 272 |
| 9 | Hoodies | 54.7% | 67 |
| 10 | Dresses | 47.8% | 1,112 |
| 11 | Coats | 46.7% | 166 |
| 12 | Sweaters | 38.2% | 96 |
A 60-point gap between jeans (98.7%) and sweaters (38.2%). Same brand, completely different fabric reality.
The Good
Jeans are near-perfect. At 98.7% average natural fibre across 1,015 products, Bershka jeans are almost entirely cotton. This is the strongest category in the entire dataset.
T-shirts and shirts are solid. T-shirts average 87.1% natural and shirts hit 81.4%. If you’re buying cotton basics from Bershka, you’re getting what you’d expect — actual cotton.
Shorts hold up too. At 77.1%, shorts are mostly cotton-based and a safe pick for natural fibre content.
The Bad
Sweaters are the worst category. At 38.2% average natural fibre, Bershka sweaters are predominantly synthetic. That means most of them are acrylic or polyester blends marketed to look like knitwear. If warmth and breathability matter, check the label.
Coats are majority synthetic. 46.7% natural fibre means more than half the composition is polyester, polyamide, or acrylic. Outerwear is expensive — and at Bershka, it’s largely plastic.
Dresses are a gamble. With 1,112 products averaging 47.8% natural fibre, dresses are the largest polyester-heavy category by volume. That’s a lot of synthetic clothing for a category where breathability matters.
How Bershka Compares
Among large-sample fast fashion retailers in Fibr’s database, Bershka actually comes out on top.
Bershka edges out its Inditex sibling Zara by 2.1 percentage points. Both beat Mango. The gap isn’t dramatic, but it’s consistent across a massive sample. Bershka’s advantage likely comes from its heavier emphasis on cotton basics like jeans and t-shirts compared to Zara’s larger formalwear and outerwear selection.
The Verdict
Bershka is better than most fast fashion for natural fibres. At 62.7% average and 45.7% of products being 100% natural, it leads the major fast fashion brands in Fibr’s database. Jeans, t-shirts, and shirts are genuinely good picks.
But sweaters, coats, and dresses are still overwhelmingly synthetic. If you shop Bershka, stick to cotton categories and always check the label — or let Fibr check it for you.
Methodology
This audit is based on 9,339 Bershka products scraped and analysed by Fibr in 2026. For each product, the fabric composition was parsed from the product page and the natural fibre percentage calculated. Natural fibres include cotton, linen, wool, silk, cashmere, hemp, and other plant or animal fibres. Synthetic fibres include polyester, nylon, acrylic, elastane, and other petroleum-derived materials. Products with missing or unparseable fabric data were excluded.
Category assignments are based on Bershka’s own product categorisation. The “polyester-heavy” threshold is ≥50% polyester by weight. Comparisons to Zara and Mango use data from the same analysis period.
