dancing in blue

Dream bit: a group of people are working to find me a fabulous red dress, I try on sexy dress, fun dress, serious dress. But it is a pale, pale blue dress that wins: long and flowing, high neck, cut-out back. I am then lost to dancing - dancing and spinning for what seems like years. I don't see my partner, only his body garbed in black suit/tux. We float/dance around and around.
