ISTO. is an independent Portuguese clothing brand that wants to change the way we dress for the better. Rather than following trends and churning out multiple seasonal collections a year, it takes a much more considered approach, offering a permanent range of wardrobe essentials that it is continuously working to perfect – from relaxed worker jackets to classic tees. Sustainably made from organic materials, these are everyday staples that are made to look amazing, fit perfectly and last longer. Scroll on for some of ISTO.'s key styles that promise ultimate year-round versatility.

Work Jacket

Inspired by one of the most iconic garments of modern times, the French veste de travail, ISTO.'s work jacket is a contemporary take on a true classic. It's cut from premium heavyweight organic cotton and softened for a beautiful feel. Team it with selvedge denim jeans for an effortless workwear-inspired look.


You can never go wrong with a pair of classic khakis and this style from ISTO. is one of the best we've come across. They're tapered to perfection and made to fit just right, without being too rigid or loose. Go smart casual with an Oxford shirt and Chelsea boots or opt for weekend ease with a plain tee and your favourite pair of canvas sneakers.

Midweight Flannel Shirt

This versatile flannel shirt epitomises the effortless elegance that ISTO. has become synonymous with. Made from super soft organic cotton, it's as comfortable as they come. A relaxed cut makes it easy to wear with just about anything, guaranteeing you'll reach for it time and again.

Classic T-Shirt

A beautifully crafted classic tee is hard to perfect, but we think ISTO. has nailed it with this one. With a slim fit, classic collar and organic cotton construction, it's a surefire staple. You might want to stock up on a few pairs in different colours.

Merino Wool Sweater

Knitted from 100% extra-fine merino wool, this crewneck sweater is a luxurious everyday essential that's warm yet breathable, perfect for year-round wear. Its lightweight nature makes it easy to layer – wear it under a jacket in winter and over a tee on those cooler summer evenings.
