1. Why spend the money?
While purchasing a bulky wool sweater for cheap sounds recession-friendly. It's probably not the most cost effective. After a while, that cheap-o sweater will lose its shape, and will leave you itchy for the rest of the winter. On the other hand, a soft, lightweight cashmere sweater — if cared for properly — will continue to fit snug against your body and keep you warm for a lifetime of winters to come. When it comes to price-per-wear, cashmere is the way to go.
2. Be 100% sure it's cashmere.
Just the word alone might be enough to send some people into cashmere-induced states of ecstasy, but check the labels before you buy. The Federal Trade Commission mandates retailers spell out the fiber content of your new winter wear. If the tag says it's a blend — or if there's no tag at all — slowly step away from the cardigan. A pure cashmere garment will be thinner, warmer, and, in the end, more worth your hard-earned money.
