That depends on a few things. If you are twinkly on your toes and can swish around the room like Ginger Rogers, not a big one. If you have a foot and shoe fetish, it is HUGE! If you are worried where they might end up and be seen after the party, this could be a problem, too.
It's all up to your talents in fashion, style, and cover stories.
The free and natural look. Very "posh" in a round-a-bout way. This look works well when you have beautiful feet, like this lady does. I have flat feet like a neanderthal. I'm not sure I would do it today because my big, flat feet have become sensitive with age. But, I like entertaining the thought :) :)
At first I thought that was a skating costume. Skaters are very fond of flesh colored fabrics because they can stay warm while still looking very racy.
I watch a lot of ice skating. Only couples, though. The men always skate face first, and the women always skate fanny first.
