One of my favorite winter dresses is this dark green one from Zara. I like wearing it, because it makes me feel very corporate with its dark green colour and its longer cut. Combined with black gives it an elegant touch yet it still looky dynamic with the 3/4 sleeve length.
Made from viscose, no matter how many extra pounds you put on during winter, the strech of the fabric will still provide you that comfortable feeling, and you are good to go.
