If there's one piece of clothing worth investing in it's definitely the sweater. The humble sweatshirt has become a high fashion hero and it all began Fall 2011 when Givenchy set the trend with their Rottweiler print sweater. Not to mention the Kenzo Tiger sweater in Fall 2012 and this fall the sweater is still popping up in several collections. The best thing about wearing a sweater is that they're chic as they are comfortable. It's not just a trend, it's actually now a wardrobe staple.
