The change from cooler spring temperatures to overheated summer weather happens quickly, so it's important to be prepared. Stocking your closet with the right clothing items is key - and you can't go wrong with flowy dresses that look just as good under a cardigan as they do on their own. These dresses will take you from one season to the next easily, all while making you look effortlessly chic. The best spring-to-summer dress is one that doesn't require a lot of thought - think bold prints that don't need many accessories or simple tank styles that can be dressed up or down.
