I am a little addicted to Polyvore. These are color combinations and clusters you select or you can just flag other's collections. In addition, the pictures have the "who makes it" so it like a shopping list. You can copy pictures from websites and make a collection list. These are some fun groups I came across. NOTE: These are other people's collections not mine--great taste out there!
You must try it. Preppy Bunny has cute items in her list!
