Why wear just one layer when you can wear ten? With temperatures varying throughout the day, spring is all about layers, and we mean serious layers. Throw on a tank top, add a shirt, a sweater, a jacket, and maybe even grab a scarf (and an umbrella for rainy days!). The key here is to look like you effortlessly raided your entire closet in one go. If you're not sweating a little, you're not doing it right. And even if you do break a sweat, all you have to do is peel back a layer or two.
