Dress idea material

i have to have the dress as something that is sexy. but yet will keep you warm in the weather.i want it to be something similar to a night dress.. the main dress material i was thinking was satin, tight fitting so it shows of the persons curves, but with a inner material similar to something like tights, very thin, and expandable but at the same time a insulator that keeps in the heat, and stop the cold from getting in.
