Both Anton and Flusser write that odd jackets and trousers cut short guys in half. I am 5' 7" and assume that in addition to the contrast in materials and colors, the busy details and patterns of odd jackets would harm my look. Does this mean I should never wear odd jackets?
Look at the photo of David Niven (the same shot that appeared in Flusser's most recent book). He's able to wear that odd jacket successfully because there's not as much contrast between jacket and trousers as the writers you mention usually recommend. Niven of course was fairly thin. A heavier man of moderate height might want to stay away from large checks on his jackets and choose something like a tan solid instead.
You should also consider casual suits instead of odd jackets to help accentuate the vertical. For example, a cotton poplin or a seersucker suit can can go to the same functions as a blazer and the vertical lines of the seersucker in particular will give you a taller look.
