We strongly oppose child-labor, and that's why all of our products are proudly made in USA by a small, family-owned business.

Our unique designs are created in Paris, so you will feel the French love every time you wear our clothing.

GOTS-Certified Organic Cotton

From seed to shelf, Big Frenchies' entire supply chain is inspected by a third-party auditor to ensure that all suppliers are adhering to GOTS standards.

Non-Toxic

The cotton we use is grown by organic farmers in an environmentally-friendly way, free of toxic chemicals.
