Description +
The Whitmore Overshirt brings together the structure of a lightweight jacket with the effortless versatility of a casual shirt, creating an easy layering piece for the changing seasons.
Designed with a clean, understated silhouette, Whitmore is made for those days when a shirt isn't quite enough but a heavier jacket feels unnecessary. Its overshirt styling gives it a relaxed character while still looking considered enough to work across smarter everyday outfits.
Wear it open over a simple tee with denim for an effortless weekend look, button it up with chinos and boots when you want something more polished, or layer it beneath a heavier coat as temperatures begin to fall.
Versatile, understated and easy to layer, Whitmore is the kind of piece that earns its place in your wardrobe throughout much of the year.

• Classic overshirt silhouette

Reviews
Honest words from folk who bought and wore it.
I wasn't really sure what to expect when I ordered the Hartwell Cardigan, but I've been pleasantly surprised by it. The fabric has a really soft, comfortable feel and it sits nicely without feeling too heavy. I've worn it a few times now over a T shirt and a shirt, and it works well with both. The brown colour is easy to wear too. Overall, it just feels like a well made cardigan that I'll get plenty of use from.
Mark O'Malley
Got the green ones and I'm obsessed! They're so comfy and feel really supportive without being heavy. Been wearing them everywhere lately 💚
Susan Decker
Bought these mainly for casual wear and walking around the city, and I didn't expect them to be this comfortable. The cushioning underfoot is excellent and there's plenty of support around the ankle, which makes a real difference after being on my feet all day. They still look smart enough to wear with most of my everyday clothes too.
Victor Bennett
Really impressed with this shirt. It's lightweight and breathable, so it was perfect in the heat on holiday. Wore it casually during the day but it also looked smart enough for dinner and drinks in the evening. Definitely one I'll be packing again.
Max Warner
Really happy with this jacket. The suede look material feels much nicer than I expected and the fit is spot on. It sits really well across the shoulders and feels comfortable without being too loose. I feel confident wearing it and have already had a few compliments. Very pleased with it.
Jesus Ramírez
I wore this to a wedding reception and was so happy with how it looked and felt. It flows beautifully when you move and the fit really complemented my shape without feeling restrictive. I also love that it doesn't feel like a dress I'll only wear once. It's light enough for summer but I can easily see myself wearing it through spring and into autumn too. Such a lovely addition to my wardrobe.

Our Conviction
"My great grandfather crossed the Atlantic with almost nothing. But he never stopped dressing like the man he was. That quiet pride is what we build every piece around. Not trends, not seasons. Just the belief that the things worth wearing are the things worth keeping."
