I really like these sites. Most clothing sites are boring and hard to navigate, but these are beautiful and easy to use.
Abercrombie & Fitch
This one has a cool photo that spans the entire page width as well as horizontal scrolling (how did they do the scrolling?) to look at items.
Hollister Co.
This one has some awesome "destroyed" effects (do you think they use a photoshop filter or do they actually destroy stuff and scan it?)
Enjoy!
