Mid-century American style.  Kind of an everyman look.

Doesn't look like he's headed to Yale, and also doesn't look like he's going hunting in the Sierra Nevada.  Doesn't look like a surfer or a high school kid either.

I think Andy Griffith, on the Andy Griffith show, is a good example of this particular specimen of male fashion of the time.  He was usually in uniform, but when not, he would sometimes be in a button down shirt, sometimes a loop collar - sometimes he'd wear a 3/2 jacket, sometimes a two-button - sometimes he'd be out in the woods and he'd be wearing jeans and Red Wing boots with a tartan flannel shirt or something, or a harrington.  Of course a huge segment of the American population dressed thus at the time and most probably weren't that concerned if not all their jackets rolled to 2.

I just read through the comments on Muffy's blog.  I'll say this, I'm proud of us for making it this far without dropping the "H" word.

HAHA.  I'm with you there.

Yes, "ivy league" has once again become a marketing ploy.  Be careful out there kiddos.
