I love wearing scarves in the Fall and your scarf against your white top really looks amazing! (thesimplemoms.com)
I also broke my own personal rule of not wearing a scarf with a necklace (which is generally because the necklace will get caught to the scarf). (have-clothes-will-travel.com)
I really love the suggestion of wearing a scarf with a belt. (myinfinitystyle.com)
