Connor McGregor lets his suit do the talking

of Huddersfield Fine Worsteds, said the company received the order for the cloth from an American customer about two months ago – with the instruction to include the explicit message.

“We can put on anything the customer wants,” he said. “We did think about it a little bit before agreeing to do it, but we decided to go ahead. It’s a bit cheeky.”

Mr Milligan said the company, which is based at Lowfields Business Park, had been cautious about publicising its involvement, but had been overwhelmed by the reaction.

“Some of our clients are happy to broadcast it and some want to keep it on the quiet side,” he said.

Huddersfield Fine Worsteds, which dates back to the 19th century, has supplied cloth worn by American presidents, business moguls and movie stars.

It has provided cloth for the outfits worn by James Bond actor Daniel Craig in Quantum of Solace and for movies including Lord of the Rings, the Hobbit, The Iron Lady and the Last King of Scotland.

Its cloth has also adorned characters in TV’s Downtown Abbey, Boardwalk Empire and Spooks. On stage, its clients include the Royal Shakespeare Company, Opera North, English National Ballet and London’s Old Vic Theatre.
