Walking In The Air by CB I Hate Perfume. First on: smells of ozone, and tickles the nose the same way bleach does. There's a faint touch of fresh greenery - pines and cedar maybe. It's difficult to mentally separate the feeling of cold, from the smell of cold. But if any perfume captures the smell of snow, this might well be it. Dry down: this perfume doesn't last for very long. It fades to the smell of clean warm skin.
