Fashion Conscious

David Bernstein wants to know:

Why on earth would you wear a sweater that only keeps the upper half of your torso covered?

Because that's the only part of you that gets cold if you are wearing a spaghetti strap top? A mini cardigan would cover the exposed back, upper arms, and armpits without adding mass to the waist area, a zone many women want to minimize. I don't even own one of these, but that sounds logical.
