Purely Listed analysis

Official homepage, sustainability page, and product feed were reviewed. The sampled products included underwear sets, thongs, and soft-cup bras, with polyester, nylon, elastane, recycled polyester, lyocell, and TENCEL terms appearing. No brand-wide plastic-free claim is assumed; sewing thread, elastic, linings, closures, finishes, and trims still require product-level confirmation. The score is brand-wide: an excellent 100% natural-fiber item does not make a mixed catalog synthetic-free.

What to verify before buying

Confirm the exact product page and care label for fiber percentages, sewing thread, elastic, labels, linings, closures, finishes, coatings, and packaging. “100%” normally describes the main fabric unless the brand provides a full component bill of materials.

Best for

Only selected pieces after checking composition; not a strict natural-fiber or plastic-free choice.

Material risk

Current product-listing risk terms detected: recycled polyester, polyester, nylon, elastane, lyocell, tencel. Continue to verify item-level composition, linings, trims, thread, waistbands, closures, finishes, and packaging before treating any product as plastic-free.
