A v-neck Sweater is a great classic piece to have. I use it mostly to layer (as I did with my go to fur vest) because it’s warm, yet still fitted so makes it easy. The plunge in a v-neck sweater also adds a bit of sexy to your look. I also love a v-neck sleeveless sweater to wear over a crisp collared shirt. J.Crew sells the best light weight sweaters here.
