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 even the father figure in your life, just in time for Father’s Day.

From the classic blue Oxford shirt by CARPASUS (Switzerland) to the brown derby shoes by Will’s Vegan Store (UK) and the neutral chinos from ISTO. (Portugal), keep reading to discover our selection of high-quality core pieces to incorporate into your daily dress for years to come.
