I think they do. Especially the loop. I don’t think I’ve ever been in a locker room - let alone needed to hang my shirt up in one. The back button does at least prevent the collar riding up.
Surely these days just a bit of extra detail satisfaction?
Something that’s in the DNA of some of us - the need to give out secret signs or give approving nods?

There are. Definitely a few Ben Sherman ‘style’ manufacturers. And probably Ben Sherman themselves made quite a big deal about their shirts having the ‘correct’ details of loop and back buttons. If only they’d been so keen to keep the collar roll.
Actually I’ve been quite happy to keep hold of a lot of my Ben Shermans. I’ve even purchased a few over the last few years if I fancied the colour or check. The collars are still just about a decent size.
I guess there would be unsavoury associations if I wore them with turned up jeans and boots. Especially as I’m bald.

Yes. I think the story is that the girl was allowed to cut the locker loop to signify that you were ‘taken’. Quite cute really. Although it would seem a shame to loose your best girl and your best shirt on the same day.

I would imagine that in the context of what else was readily available at that time they were fantastic. Not just the cut and detail, but the colours.
I believe one of the first retailers to stock Ben Sherman shirts was Edgar Jerome's in Aldershot. Still going. Most stock still held on wooden shelves and cabinets behind the counter, and until very recently hand written receipts.
Ben Sherman (the man) could see the benefit of getting his product into every corner of every high street. So lots of people could easily get hold of them. And of course have good memories tied in with what they wore at that time.
If, as some historians would have us believe, all kids in the UK went mad for mod and Ivy league clothing on the same day in 1964, it’s difficult to see all of them descending on Cecil Gee or Austins. Far more likely that they’d have headed to their local high street and been delighted to find Ben Shermans there.
Of course like high street shopping kids now, most of them wouldn’t have been thinking about the quality of the materials.

Yes they’re still there. We get the boy’s school uniform off them.
Still selling Ben Sherman and Fred Perry.
Still keen on measuring your inside leg if you go in for a jacket

Spendthrift, there used to be a tiny menswear shop in the Arcade, do you remember it ? I bought some nice reasonably priced Scottish knitwear from there. It was made by a company called Highland Glen. I also remember they also sold the original G9 Baracuta in there. I can't remember the footwear but it was definitely not American.

^ Instructive.  What 'Talk Ivy' is all about.

Runninggeez. I remember the old arcade very well. As a young kid being dragged down there by my gran to visit the haberdasher. And when a bit older we would go to ‘Cherry Designs’ in there. A bricks and mortar shop that seemed to make a living selling just badges, patches and Samantha Fox calenders. A world long since gone. Also Henry Du Bora round the corner selling old army surplus.
I imagine the shop you mention was a bit before my time (see Samantha Fox. Above)

^ Solidarity with Yuca over that style of Brooks shirt, though I've never - to my knowledge - seen even a photograph of one.  I suppose Jake's could do something along those lines.

Incidentally: the back button was a revival of an obsolete feature that had been phased out (in the 1940s I think). Whereas I'm pretty sure that the locker loop was a new innovation.

I see both as a (successful) method by Gant to differentiate themselves in a competitive market. I say successful because they seem to have been very popular towards the end of the boom years. To me though they were gimmicks really. Particularly the locker loop.

For a popover, yes something lightweight and a little youthful perhaps. For a pullover I think one of the few cloths that Brooks did back in the 1940s would probably work best. Oxford in blue or white. I think they used to do broadcloth back then too.

I’ve got a couple of Madras popovers that are summer items designed to be worn untucked, I’m undecided about them. However I have no doubts about my rejection of the sort you tuck in, they are not especially flattering for gentleman who have acquired a bit of additional ‘timber’ along the way and they just look as though something is missing i.e. buttons that go down to the waistline. Only my personal preference of course.

Woof,
I simply hate untucked shirts. I have short legs and they make me look like I’m wearing an apron. Far too scruffy.
In the madras pop overs I size up to avoid having them untucked.
