I think the one I wanted is gone.....it was a 2 button (I see the Gibbons comes in 3 b also) but single vent (do they come with side vents - do ANY Oxxfords come with side vents???).
Actually after a lot of hemming and hawing I decided to pass on the Oxxford nailhead (and boy was it hard!) for now because :
A. The gibbons in 46R is 32" long and I need a 30-31 inch hem to lengthen my legs (5'8", stubby 29" inseam), I actually just got a used Oxxford plaid suit cheap on ebay becuase it was a 45 - perfect as I am between a 44 and 46 - but it's also a Long, and measures 32". I'll probably look into shortenening it as I only paid 70 bucks so far but I obviously won't be spending $600 on a new suit that is too long!
B. The interview suit is priority one for me right now....even though a nailhead would probably work in the settings I am leaning towards (academic, small museums, etc), I'd rather play it safe. The navy, while predictable, seems the safest bet.
I appreciate all the feedback - and FP, yes, I know it's the man, not the clothes for winning the job but they DO make a difference and you must understand I was a sartorial neandrathal up till a few months ago....this forum has opened my eyes (and wallet) to a lot! So I take all the help I can get here!!!
I just put on my oldest sport coat - a very low gorge and button stance HSM golden trumpeter - and decided after not having put it on in some time (I've been mostly wearing a few ebay oxxfords and a Brooks Golden Fleece I picked up on sale, all with farily conservative high buttoin stance), I wore it yesterday and couldn't stand having it in my person!!! In past I basically never thought about it.....it was just one the few suits/sport coats I owned and they all seemed more or less alike. I've come a long way, baby.
I have decided to go with a new solid navy suit (I am biting the fiduciary bullet and - gulp! - getting a Greenfield MTM at BB), as an investment in fit and interview appropriateness...........
Thanks again, everybody - eventually I am definitely getting a nice nailhead - I actually own an old 2nd hand Oxxford blue nailhead, but its a DB and a tad small on my hips and snug in the shoulders, makes me bottom heavy! So I will look into a new one soon.
For now, one last question - If I get the solid navy but need a second suit for 2nd interview or consecutive days, would you go with my old navy chalk striped, black chalk striped or the grey crepe (remember the latter is both cheap and tired! - the stripes are just tired, but they're Oxxfords and look a little nicer). I just wasn't sure if the stripes are too ballsy, the crepe is too slouchy, and which is the bigger interview sin? I'll mention my oxxfords are all more fitted (size 44s let out), whereas the grey crepe is a roomy comfy 46.
