Slipping into a loose maxi dress once the weekend hits might be comfortable, but it isn't always the most figure-flattering choice. A body-skimming mini dress with the relaxed vibe of a sweatshirt is as easy to throw on, even if you're rolling out of bed and heading straight to brunch. Plus, the heavier fabric is perfect for cooler summer days.
