Winter white dress

I used to think about white as THE summer color, I still think it is but now I also think that it's possible to wear it in winter. I have worn this dress with ankle boots and a green military parka, with a cozy knit...but today I'm wearing it in a more formal way. Some days ago I had a meeting at the office and a girl came dressed almost like me here, her dress was a little bit longer maybe, and she looked so elegant and youthful. So white lace in winter and for an office look? Why not!
