Is it button up or button down? We know, it’s confusing. But to clear things up: A button up shirt is any shirt that buttons all the way up, whereas a button down shirt has buttons and a collar. So, all button downs are technically button up shirts, but not vice versa.

Phew. Now that that’s out of the way, we present eco-friendly brands with sustainable button down shirts (and button up shirts!) that actually fit. No more dreaded gaps in the chest, ill-fitted designs, or flimsy fabrics. These are sustainably and stylishly made—and great for pairing with a classic pair of denim jeans and brown loafers.

Want to see what else we’re rocking to the office this season? Check out our workwear for women guide for more ideas on how to style your organic cotton button down shirt (or cotton button up shirt 😉).
