P.S. Jo, in my book, a professionally dressed woman is hot! But only if she's dressed so while staying/walking/holding herself in a genuine confidently feminine way, not trying to pass herself off as man-like (think of the 'Lillith' character of Cheers or Frasier).
Some of W and my most passionate moments followed her dressing up for a presentation or interview.
You probably blew his socks off! Nice job staying mysterious.
