NWT FormKnit shell tank top, J Crew, size XS, Blue Meet FormKnit. Our softest stretch fabric forms to your body (hence the name) and stretches in four directions for a comty, flattering fit. Plus, it's never see-through and extra-smoothing. We designed it in a couple of sleek silhouettes, like this polished high-neck tank that instantly elevates anything you pair it with. And that's not all...It's crafted with a touch of TENCELT™ Modal® (an eco-friendly fiber sourced from sustainably managed and certified forests - meaning not ancient or endangered)
