Wouldn't it be nice if all clothes were clearly marked with labels spelling out "summer" or "winter"? It would definitely take the stress out of getting ready and shopping, plus it would keep us from having to constantly wonder Is this item wintry enough? or Is it too summery? Well, since we don't anticipate this imagined labeling system to happen anytime soon, we've come up with a condition that almost guarantees winter-ready looks—when it comes to dresses, at least. As you probably guessed from the title, we're talking about long sleeves. A long-sleeved dress is not only a winter must, but it can actually be a lifesaver any time you're in an outfit bind. Whether you pair it with sneakers, heels, or over-the-knee boots, it can take you almost anywhere and make dressing that much easier.
