A Styling Trick to Remember

I came across an idea I read in the October issue of Elle (which they've in turn borrowed from Marilyn Monroe) and unless I log it here, I'm afraid I'll forget it. It's for styling a cashmere cardigan: wearing it with just the top two buttons undone and without a blouse or cami underneath. I get so used to thinking of a cardigan as a jacket-y layer that it never crosses my mind to wear it as an incredibly soft, sensual, stand-alone shirt. I think this styling trick would be particularly fabulous for a casual evening out.
