Is it really winter where you live? Here in Switzerland the temperatures have been above 0° C practically all winter long, so no snow where I live. But I'm going to the mountains for skiing next week, so I'll finally see some snow. Until then, I have to wear the snow on my nails...
The white, glittery base is Essie Let It Bow. It was really hard to photograph because of all the sparkles with the white shimmer base and the translucent glitters. I used three coats. Let It Bow doesn't get really opaque, but the sparkles conceal the nail line.
For the snowflakes I used aEngland Tristam and MoYou London SNow Collection plate 04. One coat of Maniology Smudge Free Top Coat finished the mani.
