Seeing so many celebs rocking blazers has made me go a little blazer-crazy. If you want to add one item to your wardrobe for fall, you really can't go wrong with a blazer--it's a perfect transition piece for summer to fall, and there's a chance it's the most versatile piece of clothing ever. Wear it to work with a pencil skirt and heels, wear it on the weekend with jeans and boots, wear it on a date with a lace dress and wedges. Ready to blaze a new fashion trail?
