When it's time to spruce up your wardrobe, you don't necessarily have to reinvent the wheel. Instead, consider popular styles that you might not have given a second thought. Enter: the halter top. The classic silhouette shows off the shoulders and can make any woman look instantly sexy. Some halter tops have a more dressed-up look with satin- or silk-like fabric, and others can actually be super casual, like those with a sweater-like material. Whether you pair them with jeans, a skirt or trousers is up to you, but luckily, you really can't go wrong with whatever you choose.
