Short answer
Care for dresses depends on the chosen cloth and its care label. Ask the tailor for instructions for the exact garment; follow the label and avoid heat or cleaning methods it does not permit.
Silk-family cloths are cleaned sparingly and stored on shaped hangers; the tailor confirms the routine for your cloth at handover.
Follow the care label for the chosen cloth and ask the tailor if the instructions are unclear. Storage, ironing, steaming and cleaning advice can vary by fibre and finish.
The itinerary is a proposal: months are planned, dates and venues confirmed individually. Final quotations are confirmed in writing before you commit.
