For: Owambe / afternoon reception / a 40th where you want colour
Strong shoulders, clean pockets, colour that photographs beautifully in British light. The most useful entry point if you want presence without commissioning bespoke.
For: Aso-ebi where you want a two-piece rather than a robe
The version I would choose when the family cloth is strong and the room is warm. A senator cut from the group cloth reads as part of the set from across the hall and as tailoring up close.
Indicative UK market range: £280–£600 to make up, cloth excluded
For: Reception after a ceremonial first look / late supper / a party indoors
An unstructured ivory jacket over a black trouser is the fastest change of register there is. It reads evening without asking you to wear evening dress.
For: A garden wedding, a naming ceremony, or the day after the main event
A belted safari jacket in olive gives you a jacket without a suit's formality. It is the most photographed thing I own at daytime events, and the belt is what makes it work.
For: Black tie in summer — an outdoor dinner, a destination wedding after dark
An ivory jacket over black trousers is the only real variation black tie allows, and it is for warm evenings only. Matte cloth, shawl collar, and nothing in the buttonhole.
