Short answer
Choose cloth for the places and seasons where you expect to wear these womenswear suits. Ask the tailor about fibre, weight, weave and care for the specific options; a city's name alone does not determine the right cloth.
Four-season stretch wools for working weeks, silk–wool for occasion suiting, with linings chosen for how the garment moves when you do.
Danish December takes flannel and layered knitwear under an unstructured coat; the summer conversation begins for delivery before June — high-twist wool and an unlined jacket.
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.
