I have a pair of lucky panties. Back in the days of my life as a high-flying, highly paid ad exec (versus my current status as impoverished startup entrepreneur), I bought a pair of Tom Ford for Yves Saint Laurent sheer black chiffon bikini panties with the YSL logo on the front in diamanté. I wear them to important business meetings and when I want to get laid. They have a very good track record on the business meeting front, and a 100% success rate on the other one.
