A lace top is a great choice for the holiday party circuit. Carry it with you to work, and you can change into it before evening get-togethers, pairing it with a pencil skirt or trousers.
All of these tops have some embellishment to them, but if you prefer something more classic, there are some great options out there.
French Connection made the same top in short sleeve and long sleeve, both at a Hill Staffer price. Madewell also makes a simple lace tee for under-$100. And if you need something in a plus size, this v-neck Karen Kane top is lovely.
