The coach most clearly described as wearing a suit in every match of this current World Cup is Japan’s Hajime Moriyasu, who has been noted for insisting on a crisp three-piece at every game.

A few other coaches are also highlighted as regular suit-wearers, though the coverage is less absolute than Moriyasu’s:

  • Uruguay’s Diego Alonso
  • Germany’s Hansi Flick
  • Cameroon’s Rigobert Song
  • France’s Didier Deschamps, who is described in tailored formalwear in match coverage

Quick Scoop

If you mean the one who has kept the suit look for every single match, the answer is Hajime Moriyasu.

If you mean the broader group of suit-first coaches at the tournament, Moriyasu is the clearest standout, with several others also dressing formally on the touchline.

Why he stands out

Moriyasu is specifically singled out in current coverage as the coach who has “insisted on a crisp three-piece at every game”. That makes him the strongest match to your question, since the wording points to consistency rather than just a one-off suit appearance.

Other formal dressers

The same reporting also places Diego Alonso, Hansi Flick, and Rigobert Song among the more formal managers at the tournament. Didier Deschamps is also described as wearing a tailored navy suit in opening-match coverage.
