Damn, I just wanted to say that there is no need for pockets because a well dressed man wears a waistcoat. Which hides the shirt, because actually it is underwear. Narfnarfnarf.

A back button indeed has a function and besides that, it is a nice touch. If you look at it that way, ivy offers the person behind you a lot to look at: cap with back-buckle, shirt with back button, trousers with back buckle... a lot going on there, actually.

Re pockets...I never thought about that. I think, most of my shirts have a pocket sans flap. Often, I put underground tickets and little notes in the pocket. I forget about them, they get washed and fill the pockets with lumps of paper.

Thinking about it, maybe an open pocket is better because it is easier to put things in them.

In my experience, it seems the back collar button is usually seen more on casual short sleeve shirts, like old "Ivy Leaguers" and such.  That is, it seems like when I see a shirt with a back collar button, it's on a shirt I wouldn't wear a tie with.  Input?

I never have a problem keeping my tie or the back of my collar in place without the button.  Seems to me if you route the tie over the button it would be hard to keep the tie from getting bunched up once the collar's folded and buttoned.

Now the locker loop has always puzzled me - Try using it and you will find it really creases up your shirt. Much better to hang your shirt by the collar as you would a jacket.

I know what you say to be true, however if you try to hang your shirt up by it you'll put on a crumpled rag when you return from the showers. It's probably positioned in one of the worst possible places to hang up a shirt.

I think the locker loop is a nice touch and of more practical use than the back button.  I don't think that hanging your OCBD by the loop causes extra crumpling.  Let's face it, your shirt will be pretty crumpled anyway by then through being worn during the day.

An often repeated story - Also that girls would pull the fruit loop / fag tag off the back too in High School.

Who knows ?

A bit like the Claddagh ring code ...

How true is that one ?

I wear a Claddagh  and my ring does indicate that my heart is taken.
