Two button isn’t my natural inclination. If I’m honest I’m far more likely to let detail slide on a true three than a two.

That said I couldn’t be happier with my two button Pendleton blazer. I think I’ve previously said it was gun club, but when I last pulled it out I realised it’s actually brown/blue gingham. US made, virgin wool, good lapel. Soft shoulder and centre vent. The button stance is more akin to typical 50’s/60’s than 70’s/80’s

In a fit of madness I asked my tailor if he could add a button. In a further fit of madness he agreed. Then we both decided it was perfect as Pendleton intended.

Perhaps he’s just a really good tailor and gently steered me to my senses?

Strange thing is it was brought new, but I’ve never seen another like it. Even in Internet Land.

Much as I was in love with the 3/2 I never objected to two-button.  The problem was, finding anything that could be tried for size before buying. 
Nowadays, I'm afraid I'm as indifferent to jackets as I am to ties.  I'm more or less living in my duffle coat at the moment (college scarves in rotation), and the two jackets I still own, both two-button, won't see much action before mid-spring.
Those mentioned above, by TRS, Spendthrift and Robbie, sound delightful.  I seem to remember Frosty commenting on a Cricketeer sported by Jason Jules at some creative shindig or other.  It's very much what I'd have gone in for a dozen or so years ago and still regret selling the unlined Press herringbone I bought from J and PS back in the summer of 2012.  I don't know whether TRS vaguely remembers it.  He was there at the time. 
Now, though, the pair that I have are unlikely to be joined by any others, unless something Boomish in plaid crops up on Ebay.  That I could be tempted by.

I wonder how completely dominant the three button jacket actually was during the ‘boom years’, or whether it’s a construct that Ivyists have applied in retrospect? All my jackets and suits are three button, as that is what I have acquired since I’ve made a conscious effort to adopt my understanding of what is the Ivy look, which I have mainly picked up from visits to JS, the internet and of course the little white book - the thoughts of Chairman 2RS. I also I just like the different quirkiness of the 3/2 roll arrangement. I suppose I’ve worked on the basis of why have two buttons when you can have three?  Having said that, if I came across a two button jacket like the one discovered by 2RS and in such serendipitous circumstances, I would also be obliged to buy it. Such items are little bits of history and a testament to the golden time of American manufacturing so we have a duty to errrr … *curate* them.

The union label I do care about, come what may.
