I have always had good luck with Van Huesen shirts. They are reasonably priced and you can find them all over. They stay pretty wrinkle free with just a touch up with the iron.

I've had fine luck with Oxford cloth shirts from VH, but most of their pinpoint shirts are extremely thin, with the white and pastel colors being to the point of being see-through. This is my main complaint with most lower end designers and store brands.
