The BCBG Maxazria site does something very few apparel sites seem to be doing ==> help you find just what you’re looking for. While most sites only let you pick a category like tops or pants, the “Shop Trends” menu item opens up to let you shop by Lace, Floral Paint and more. The results pull up everything within that trend – whether its a dress, a belt, or a pair of shoes.
If a healthy dose of helpful relevance wasn’t enough, they also have fun videos in most of the category headers. Very much a best practice.
