Demonrail, over the past couple of years I've checked out a hell of a lot of polos. I've found TWO brands that are any good: J. Crew and Fred Perry. The latter is harder to find and more expensive, at least here in the states. J. Crew makes very classic, traditional polos that fit slim. Another advantage with J. Crew is that there's never an ugly logo visible anywhere on the outside of the shirt. Logos ruin even the best polos, I think.

Whatever you do, buy your polo in a slim fit. There's nothing worse looking on a guy than a baggy polo. And do not--DO NOT--wear a tee shirt underneath.

Also never ever tuck them in, unless you wanna look like an office-cubicle geek.
