Men’s Smart Casual Fashion, Done Sustainably

On the hunt for men’s smart casual fashion? We’ve rounded up more ethical and sustainable options to kit out your fit for any occasion.

The timeless taste of men’s smart casual fashion

Many moments in life fall into that wardrobe grey area between trackies-and-a-hoodie and full-on-business-suit, known as “smart casual”. If it sounds pretty ambiguous, that’s because it is: think of smart casual as a sophisticated upgrade to casual clothing that you could technically wear day-to-day. We love it because, by nature, it rejects passing trends and embraces a timeless and elegant look for anyone who digs menswear.

If you’re one of those conscious consumers who wants to consider people, the planet, and animals in your decisions when purchasing new, take a breather. We’ve done the hard work for you and dug into our ratings to find the best ethical and sustainable menswear brands creating smart casual attire worth investing in.

Ok, technically, the most sustainable menswear—smart casual or otherwise—is what’s already hanging in your closet (or someone else’s). But when you’ve exhausted your existing options, this list is a great go-to for you or for gifting.

From classic Oxford shirts to brown derby shoes to natural chinos, keep reading to discover our selection of high-quality core pieces to incorporate into your daily dress for years to come.

A note on degendering fashion

While this article may be addressing keywords on men’s smart casual fashion, here’s the simple truth: clothes don’t have any gender. It sometimes seems silly how the industry ascribes gender to inanimate garments like t-shirts and socks. We believe people of all genders should be able to express themselves however they want, regardless of the binary marketing. So when you use our directory to search for brands, we automatically deliver search results without any consideration to gender. If you still want to find products labelled as menswear or womenswear, you can use our filters.
