Leave it to Jennifer Lopez to make even a long-sleeve top look sexy. The superstar was spotted in the Intimissimi Boat Neck Ultralight Top, which just so happens to be available on Amazon. While Lopez strutted her stuff in a nighttime look, this lightweight top is a staple you can break out for every occasion, day or night. What makes this long-sleeve top so special is that it's incredibly soft, lightweight and breathable. It's made mostly of modal, which is known for having a silky feel. The rest of its makeup is cashmere and elastane, so you can count on stretch, too.
