If you buy only one piece of clothing for this spring, make it a pair of loose, straight-legged jeans. The classic silhouette and relaxed fit make them a go-to for any situation, whether you're running errands or going out to dinner. Jennifer Lawrence's latest casual look is a perfect example of this: the star wore a pair of loose denim jeans that look so comfortable and chic we knew we needed to find them for ourselves. Lawrence was spotted wandering around New York City in what might be the perfect laid-back spring outfit: jeans, a colorful tee, bright cardigan and comfy tennis shoes.
