The guys over at JoBlo have an exclusive video journal from director Zack Synder:
To put it simply, there is an enormous amount of characters that populate the many time periods and environments of the Watchmen world. Although we encountered many challenges while making Watchmen, one of the most interesting and rewarding was creating the wardrobe for all of those people. This is the second time I've had the pleasure of working with Costume Designer Michael Wilkinson. Once again, I'm amazed by his talent and dedication. Take a look.
-Zack
