11 Ethical Underwear Brands for Him and Her

Refreshing your wardrobe, whether it be out with the old or in with the new, is like a breath of fresh air; liberating, cleansing even… but what about that underwear you’ve had for longer than you would care to admit? Those undershirts starting to yellow in the armpits? Those favorite pairs of socks thinning in the heel? Must I say that nagging bra with an exposed underwire that should probably be replaced? 

Per the industry, the standard rule of thumb is to refresh undergarments every 6 months to one year, depending on the wear they receive. That being said, it might be time to restock those neglected underwear and sock drawers.

Eco-Stylist believes in rejuvenating your drawers with undergarments that not only look and feel great on, but are manufactured and distributed both ethically and sustainably. Our certified brands put an emphasis on how their clothing is made, as well as how the people making them are treated.

From the following list of brands, shoppers can purchase undergarments designed to make them (both him and her) look and feel great as a conscious consumer.
