If you're plus-sized and looking for extra roominess, XXL is your go-to. Our onesies are made to flatter a wide range of shapes with their comfy, flowing silhouette. As you browse our styles, you’ll notice how they hang differently depending on the wearer’s height and shape — and that’s exactly the magic of a LUSH fit.
