I haven't purchased it, but Leslie said it is the same as, or at least similar to, an article she did awhile back. In it, she listed 25 basics, as dorish said above. Then she lists the different combinations you can make with the different pieces. For example: white button up + neutral skirt + accent cardigan, accent t-shirt + casual jeans + casual blazer. She includes pictures to give a visual idea of some of the outfits, along with accessories. She shows how to make at least 100 outfits from those 25 pieces.
