Season of fall and winter is the season of layering for style and warmth. One of the hottest layering fashion item is a vest that can go over shirts and under a outerwear. Our favorite pick is this knit cropped vest cardigan fron American Apparel. This soft and neutral colored knit vest is thin enough for layering but also provides the extra warmth that you need. Open front with buttons and v-neckline allow more versatile use of this vest. Wear it over a sleeveless or long sleeve blouse. You can pick a blazer or a more casual jacket over the vest. There are just too many options and styling you can do with this vest!
