Editorial
Layering a sleeveless dress works best when you check the armhole, shoulder width and fabric first, then add a soft cardigan or a structured jacket. I go through COS dresses, cardigans and jackets, and how to test the full outfit by raising your arms and sitting down.

Editorial
Relaxed shirts, polos and wide pleated trousers for men in silk blends, linen and soft neutrals. Fluid pieces that hang loose and layer easily.

Editorial
Long coats to buy before winter arrives, with notes on wool content, lining and how to size for layers.

Editorial
Everything in warm white and bone — a silk cami, wide-leg trousers, a structured shoulder bag — worn as one unbroken thought. The kind of tonal dressing that looks accidental and takes real intention.
