hey folks, I just picked up a JCrew tweed sportcoat and a BR corded blazer this past week (both in Short length) and was wondering about the frontal appearance and whether or not I got the sizing right. The fit of both seems pretty much spot on in the shoulders/chest but I'm wondering how the front should appear. I rarely wear a suit and this is my first time buying a casual blazer.
Specifically, I'm referring to the front opening beneath the lower button (2-button) and how it should appear, for example, if one had their hands in their pockets. Should your belt/tie/shirt show a little or is this considered improper? Of course, only the top button is buttoned and I was referring to this 'proper fit' image I found on esq. as a reference point:

If I place my hands straight down in front of me as in the picture I can achieve the so-called "just right" look, but when I place my hands in my pockets, the appearance is more as such:

Can anyone please chime in as to what is considered a proper, traditional aesthetic for how this should appear? Should I worry if so much is visible below the second button or is this considered ok? Im wondering if I need to try out a Regular length or if the Short length I got is alright. I'd take pix but I'm at work atm. Thanks for any feedback.
