I'm a big fan of American Apparel polo shirts. I find them well cut, long lasting & they are made in America

I'm with One Trick Pony here in that I don't hate polo shirts, but at the moment am not really that inspired by them. Of the makes that I do own, the best one I have is a no logo white pringle one. Its really well made, not too baggy and most importantly the collar stays flat, it doesn't curl up during wearing like Fred Perry's, Burberry's etc.

Lacoste, for awhile until they came just another brand, just another sigil replacating itself like a Burroughs's word virus, had some distinguishing qualities in the polo shirt.  They sold out so bad, its annoying.

They had "the" classic summer aftershave for men, reminiscent of the Mediterranean, and now, they've take it off the market and there's a load of synthetic shit instead, smells like its come off slag heap in Merthyr Tydfil. 

Lacoste, the clothing equivalent of Paul Weller.

The American Apparel shirts are far too Superbad to be Ivy; OK for younger chaps with beards and volumes of post-ecstasy generation poems tucked into their back pockets I would have thought. The AA plain cotton t-shirts are quite good though.

I have a couple of pique cloth short sleeve button-downs from Brooks from a few years ago and these might be the answer for those intent on putting another twist on the classic tennis shirt. They were made in the far east so that might rule them out for many on here. The navy gets a lot more wear than the white, principally with seersucker or stone/tan poplin. I always wear them with the top button closed as I would a tennis shirt.

^  the ivy shops in richmond and windsor always had a lot of viyella shirts. mostly cotton with some wool if i remember correctly. superb quality and indestructible.
