Pre-Let It Go Elsa is about pure repression, everything about her is uptight. You know her clothing reflects this as well, she wasn't wearing clothes to accentuate her curves to but to flatten them out, to conceal. Her ice dress was the G-rated equivalent of her going nekkid in the snow, she let it all hang out, she made the dress to as curve-hugging and free-flowing as possible.
Also, you know what she was doing in the ice castle all by herself? Masturbating. She's never jilled off, she was too scared she would lose control and freeze over the entire castle. Once she took the throttle off you know she was letting go of a decade of repressed sexuality up in her throne room.
