While my initial impulse for holiday parties is short and sparkly (seriously all of the sequins please!), there's something to be said for going the more demure route. Sequins are flashy, but longer, full skirts are unexpected and more dramatic. The details really make this look so fun too--spiked belt and cheeky tights definitely keep it from being too staid.
What are you dressing up in this winter?
