What┬'s a pretty young thing to do in this season┬'s sea of little black dresses? Decide that white is alright, of course! Make sure you┬'re seasonally correct with black accessories like Sienna did (above) with her Christian Louboutins. Your choice of fabric is also of key importance┬--winter white requires a heavy texture or fabric. Keep in mind, this is not the garment you┬'ll take on your December vacation to the Four Seasons in Wailea.. If you want to dress up your ensemble you can go for some minor embellishments a la Brittany Murphy, seen here at a recent Hollywood premiere. Need outerwear options? If you┬'re feeling fancy you can do fur or grab a fitted jean jacket if you┬'re in a casual mood. The result? Just some simple white heat darling.
