I need to split off a quick question from the "Buying a cashmere sweater" thread. The background is that I'm a fair-skinned guy of Chinese descent and expect to be in the East Coast for one winter, thus am looking for at least one good sweater. So: If you were to have only one good sweater for fall and winter, what color would it be? I figure dark blue and gray are the safest, most flexible choices, but what else is possible given my complexion? How about lavender and purple, or are those a bit tough to match? It's probably not rocket science, but I've never owned nor needed a sweater, and saw the J.Crew sale posts about dark green, persimmon and hot pink sweaters, so wanted opinions about what people wear.
