The sweater I've had the longest (late 80's, high school) is a camel colored, lambswool, deep v-neck. The second is a heathered, light grey cashmere, deep v-neck. (I wore that like crazy in college, as did a girlfriend. Fortunately, I took that with me when she got the Rhodes and dumped me, hard. It's still in great shape. My heart, not so much.) I highly recommend those two to start. I still have them and wear them at times, but my favorite sweaters now are a merino full zip in dark charcoal, a merino three button polo in burgundy w/ black flecks, a rustic shawl collared cardigan in medium blue, and a cashmere crew in light, heathered gray.
