Besides wearing the same type of shirts all the time (different color), Martha Stewart’s style has always been characterized for addressing the down-to-house business women and appealing to the modern housewife.
Her style feels very homey with generally light typefaces and matte backgrounds mixed with pastel/seasonal tones and themes portrayed with a classic and organized cover layout (Usually portraying herself doing whatever the book says she is doing.)
Very simple and very readable cover usually trying to represent how simple or easy to follow the content of the book might be.
