M&S = court appearance
You’re clearly unfamiliar with the world of British criminal justice!
Lifestyle criminals, that is to say low level types who take up the majority of the courts’ time wear whatever they like. Those that do wear suits used to favour the likes of Burton and Next. But, now that the likes of ASDA are selling garments that purport to be suits, they’ve taken over as tailors to the criminal fraternity. I see the same £30 effort again and again…boxy, no vents, you know the score.
M&S suits are pretty decent, especially the £200 plus range. They’re not Saville Row standard, but then you wouldn’t complain that your new VW Golf wasn’t a Rolls Royce.
