Burberry London ($895), burberry.com.
It took 20 years and two wars (the Boer War and World War I) for Thomas Burberry to perfect his design for the trench coat (gabardine, epaulets, D-rings—you get the idea), and it's pretty much remained the same since the Treaty of Versailles. It took Burberry's current creative director, Christopher Bailey, about five seconds to start thumbing his nose at tradition. Since Bailey arrived at the British fashion house in 2001, he has continually updated the classic, tweaking its form without abandoning its original purpose. For fall, Bailey trades khaki for olive and hacks off more than a few inches in length, redefining the trench for today's officer and gentleman.
