In cold weather, women rely more on outerwear to make a fashion statement. And although few women look like actress Marie Cotillard in a coat (pictured here) whatever your shape, there's a style that will flatter you most. Also keep in mind that you may need more than one coat for the season. For example, if you're wearing a dress and have exposed legs, a longer coat will keep you warmer. The same long coat, however, can look bulky with a heavy sweater and jeans.
