We’ve worn breezy button downs from the top sustainable brands for years — these are our favorites for women made with organic cotton and a perfect fit, at a variety of price points.
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 organic cotton 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.
What makes a perfect organic cotton button down?
Choosing a sustainable button down shirt can be one of the best clothing purchases you make as they are a super versatile piece — especially if you’re building a capsule wardrobe. Specifically, organic cotton button downs are made with high-quality and pesticide-free natural fibers that last long after many wears and washes, are breathable on our bodies, and are biodegradable, which is better for our planet. Since they’re easy to style and pair with so many outfits, it’s safe to say you’ll be making tons of use out of your sustainable cotton shirt!
When selecting a cotton button down, it’s also helpful to find out how your shirt is crafted; ensuring your new piece is made using strict sustainable and ethical practices like minimal water usage, nontoxic dyes, and recycled materials help support responsible supply chains that provide healthier environments for the workers who make our clothes (and for the planet itself).
Of course, one of our favorite ways to shop — secondhand — is a great go-to for adding fun and high-quality button downs to your closet. But, if you’re short on time or looking for something specific, these eco-friendly brands carry our favorite women’s organic cotton button downs (and ups!) for all occasions.
