Where this brand isn't perfect

Straight talk

Where Not Basics isn’t perfect

Check firstNot a certified B Corp

Not Basics is not a B Corp. The brand-level labels are thinner than the product-level ones.

What the label won’t tell you

The questions sensitive skin actually asks, answered

✓ 183 of 183 styles scanned, no sampling ✓ 98% plant · 2% synthetic ✓ read from the live product feed, not the marketing page

Are there hidden chemicals against my skin?

183 of 183 styles scanned: zero PFAS, zero formaldehyde.

Is "sustainable" just greenwashing?

“Eco” and “green” have no legal meaning, and thousands of unverified claims flood the market. We scanned 183 styles from the store’s own product feed and publish a score only at full coverage. We read certificates, not adjectives.

Is "100% cotton"

actually

100% cotton?

Most “cotton” underwear hides elastane or spandex in the trims. We read the stated fibres on 183 of 183 styles, thread by thread: 98% plant, 2% synthetic.

Will the elastic bring me out in a rash?

Latex and rubber waistbands are a top trigger for contact eczema. Elastic check across the catalogue: Elastane. Spandex, flagged red in the Skin-Safe section above.

Where's it really made,
and by whom?

Named farm and factory
GOTS chain of custodyTraceable back to the cotton

Traceability on record: see ledger. We publish the full sourcing chain and the honest red flags, including where sources conflict.

Am I shedding microplastics onto my body?

Synthetic underwear sheds plastic fibres onto your skin and into the water with every single wash. Not Basics is 2% synthetic, so yes. These styles shed. Wash cool, use a guppy bag, and favour the plant-fibre options in the range.

Sources: consumer research on formaldehyde in easy-care fabrics (~9% of people react), PFAS in water- and stain-resistant finishes, and hypoallergenic underwear for eczema and contact dermatitis.

CHECK IT YOURSELF

Check this brand yourself

What it costs per wear, who actually makes it, and how much the fabric sheds.

What it costs (£)

Times you'll wear it a month

Years you'll keep it

Repairs / alterations (£, optional)

How synthetic is it? (polyester, nylon, acrylic, elastane)
