What Makes Our T-Shirts Special?

Making a Difference

By choosing organic cotton clothing, you are using 50% less water, 50% less energy, and 46% less CO2. By choosing Big Frenchies, you are also planting a tree with every order.

Ethically Made in USA

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

Designed in France

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.

Amazingly Soft & Durable

With no chemicals to weaken the fibers, our organic cotton clothing is more durable and softer than conventional cotton clothing, which makes it a great choice for people with sensitive skin.
