Breakdown
Composition
72% Tencel, 28% Nylon
Plastic-based — sheds microplastics in wash
Synthetic fabrics can contain BPA, which mimics estrogen. Studies have found BPA transferring to skin through sweat contact.
This fabric will take 200+ years to decompose. That means a shirt you buy today will still exist in the year 2226.
Tencel (score 82) is carrying this blend. Nylon (score 58) is pulling it down.

How we got there
Base for Dresses: 50 expected wears.
× 1.00 for Tencel (mid-durability fiber, durability 74).
= 50 expected wears. $148 ÷ 50 ≈ $2.95/wear.
Missing GSM — this is a category-level estimate, not garment-specific. Expect ±30% variance.
Real life is messier than a formula: how often you wash, how you wash, whether you wear it inside-out, dry on low — all of it shifts the number. This is the ceiling under reasonable care.

Health & environmental impact →What this score doesn't measure
- ×Fiber grade. Staple length, micronaire, strength. "100% cotton" could be short-staple upland or long-staple Pima — same label, very different fabric.
- ×Yarn processing. Singles count, ply (single vs two-ply), spinning method (open-end vs ring-spun vs compact), mercerization. Invisible from any label.
- ×Knit / weave structure. Single jersey vs interlock, knit tightness. A loose knit pills; a tight knit lasts.
- ×Fabric weight (GSM). One construction signal among several — and high GSM can come from loose cheap yarn just as easily as from fine tight yarn. We have it for blank manufacturers, rarely for retail.
- ×Pre-shrink processing. Sanforized cotton shrinks ~1%; non-sanforized can shrink up to 10%. Not visible from the composition tag.
- ×Construction quality. Stitch density (SPI), seam types, collar geometry, manufacturing tolerances (AQL). These often matter more than the fiber itself.
- ×Specific chemical loads. Health Impact flags "likely PFAS / possible formaldehyde" from composition × category — we don't lab-test individual SKUs.
We rate the fabric, not the garment. Composition is the floor of what you're guaranteed to be getting — most shoppers don't have that.
