If I am coming to your home then I try to dress nicely but still a bit conservative. If I am going to a hotel I kick things up a notch.
The most scandalous thing I wore out in public (his request) ended up getting toned down (lace blazer and ruched dress was pulled down longer) because of the family friendly venue we were meeting at. I did have a fabulous time that night though because of what people couldn't see.....
What my friends wear only matters if we are going out in public for drinks or a meal. Otherwise, I'm mainly interested in what's underneath...
