Short answer
Choose cloth for the places and seasons where you expect to wear these wardrobe chapters. Ask the tailor about fibre, weight, weave and care for the specific options; a city's name alone does not determine the right cloth.
The wardrobe conversation reserves cloth across the whole programme in one sitting, balancing weights and colours so every garment agrees with every other.
Light is the rule — open weaves and silk blends by day — but Cannes conversations always reach the evening: a midnight-blue dinner jacket that survives the sea air, unlined and certain.
The full cloth books span fresh open weaves through four-season high-twist to winter flannels and cashmere blends. Bring the tailor your calendar; the shortlist comes back two or three cloths wide.
The itinerary is a proposal: months are planned, dates and venues confirmed individually. Final quotations are confirmed in writing before you commit.
