Some photos I found, I didn't find the luncheon event. I forget about the horrid formal gown HM wore when attending the banquet with the President. I got a quick call from my mother who was horrified at it.
I read an article several years later that it was an attempt to bring the Queen's wardrobe up to the "Diana" level. Well, it failed. We never saw many of the outfits again, especially that gown.
I remember Anne wore a gown in the "Diana" style and that gown was relegated to "never again" status, too.
