I learned from Scott Schuman, photographer and owner of The Sartorialist blog, that fisherman sweater on girls has to either be undersized or oversized. In his words, let it be small like it is borrowed from your little brother or large like it is borrowed from your dad. I can't agree more. The fisherman sweater style plays with thick patterns on wool that can immediately make a normal sized person look bulky. Sometimes, the trick to wearing it is going sizes smaller or bigger. Try both looks and see what works for you. I think of preppy girls going smaller and free-spirited ones going bigger! Which one would you rather wear?
