For some of us Brits, Martin Shaw the lead actor's attempt at a North-Eastern England accent was rather amusing.hmmm, interesting. It looks like it would take adjusting all through the day.
When I saw the title "Gentlemen's Attire",....I was thinking more then just a knot. So I will expand on a man's attire. If I had more leisure time and money I know how I would dress. A few years back flipping through the channels I came across a British detective series called George Gently. Who ever did wardrobe for the show did one heck of a job dressing the man, leisure and formal. I hunted down the series just to see if it held through the show,....and the show is a good detective show.
The opening credits shows multiple situations in different attire.
