Is this thong really 100% cotton?

Yes. The fabric is 100% organic cotton jersey, with no synthetic blend listed. That makes it breathable but less stretchy than cotton-modal or cotton-elastane thongs.

How does it compare with a seamless thong?

It is a cut-and-sew cotton thong, not a seamless one. Under thin leggings or tight dresses, seams and edges are more likely to show than on a bonded microfiber thong.

Will cotton jersey hold its shape?

Cotton jersey is soft and breathable but has limited stretch recovery. Expect it to relax with wear and washing more than thongs with elastane.

Shoppers who want a plain black everyday thong in a natural fiber and prefer organic cotton over synthetic fabrics.

Does it work for sensitive skin?

The cotton jersey is a breathable natural fiber with no lace or mesh trim, which many people with sensitive skin prefer. The brand gives no specific skin or allergy claims.
