Lululemon Align™ Dress Belgian Blue NWT Size 6, sold out color

You can keep your exercise dress on while you go to the bathroom this summer. Yes, really. Lululemon's new Align Dress ($148), which features the same, velvety soft fabric as its coveted leggings, comes with the smartest, simplest shorts liner that'll have you ditching the strip when nature calls. Imagine that?! Pro-potty shorts aside, it's also ridiculously cute and even more ridiculously comfortable. Between its next-to-nothing material, its sculpting, lightweight support, and its cute colorways, it's pretty much *the* perfect exercise dress. In fact, it's left me and my fellow Well+Good staffers nothing short of amazed by how dang pleasant it is to wear, move, and go to the bathroom in. Albeit a bit expensive, it's the one-and-done piece of clothing you won't want to (or have to) take off this summer.
