Oh god no, never horizontals. As pudgy as I am that'd just exacerbate the shortround aspect, lol.
Okay, zip ups strictly, good to know. Is plaid okay? I've always had a borderline obsession with it, so that's what I'm probably going to gravitate towards at the Salval. Oh yeah, stupid question that's probably been addressed before: does it matter which side the buttons are on? I've never paid much attention, when it comes to button ups, what section I was getting them from (and, admittedly, because 70% of my shopping is done at thrift stores and NO ONE ORGANIZES THEM WORTH CRAP) so I'm worried that might be giving me away?
