An ivory crewneck sweater is a three season piece for me. I layer it under jackets and scarves in the colder months, and wear it solo in the early spring. This Magaschoni sweater is a good choice. Charter Club from Macy’s has an $80 cashmere sweater that comes in a myriad of colors. J.Crew also makes their popular Tippi sweater (also in petite) in ivory.
