The corduroy is heavier than I expected in the best way and the elbow patches give it real character. Wore it to a dinner and had three compliments before the starters. True to size on a 40R.

These have quietly become my summer uniform. The stripe is subtle enough to wear with anything and the drawstring actually stays put. Got them in medium and the length sits perfectly just above the knee.

Bought the olive after seeing it styled online and it is even better in person. Broken-in feel from day one and it sits perfectly over a tee or a hoodie. The faded cotton looks premium, not cheap.

Proper weight linen that drapes beautifully and never goes see-through. I rolled the sleeves and wore it open over a tee all weekend. Runs slightly relaxed, which is exactly how I like it.

Completely obsessed. The red is rich and the little daisies are so pretty in person. The tie straps let me adjust the fit so it skims rather than clings. Wore it to a garden party and basically lived in it.

Really comfortable from the first wear and they feel sturdy without being heavy. The adjustable straps make the fit easy, and the black goes with almost everything. I wore them all day on holiday with no rubbing at all.

The texture in the fabric is what makes it look far more expensive than it is. Great for warm evenings, breathable and holds its shape all day. Paired it with the linen shorts and felt sharp.

My new go-to. The cotton is soft but substantial and the buttons feel solid rather than flimsy. Fits true to size with a bit of stretch through the shoulders. Already eyeing a second colour.
