Short answer
Set the formality, palette, budget and decision date with the couple, then check lead times for each person’s outfit. Party members may need different providers or fitting routes, so confirm individual measurements, delivery dates and responsibilities before placing orders.
The decision architecture
One decision-maker (usually with the groom): register, palette, budget ceiling. One deadline: party orders enter with or immediately after the groom’s commission — see the timeline. One channel: sizes, measurements and fittings collected centrally rather than by nine separate conversations. The weddings that go wrong here go wrong in the group chat, not the atelier.
Mixed bodies, one register
Party members can keep the same formality while choosing garments and fit options that suit them individually. If you want group fittings, ask the provider whether dates and locations can be coordinated; do not assume every member can use the same route.
Money, honestly
Set the budget openly per man, early: party costs are real and vary by member. Options that work: the couple funds cloth and making for a matching piece; or each member buys to the agreed register (their garment, kept afterwards — a genuine gift of a working suit). Either is respectable; surprise invoices are not.
