Short answer
The appointment plan for a trouser fitting in Brussels depends on the garment and provider. Confirm appointment length, measurement and cloth-selection steps, venue, any fee and the quote process before booking.
The trouser fitting is a sitting test: rise and thigh room are checked on a chair, the break pinned against your shoes, pockets chosen for real use.
Bring the occasion, preferred delivery date and any fit notes you want to discuss. The appointment plan, venue, quotation and any applicable fee are confirmed directly; the commission begins only after you accept the written quote and required deposit clears.
The itinerary is a proposal: months are planned, dates and venues confirmed individually. Final quotations are confirmed in writing before you commit.
