This eco-friendly tank is a must-have if there ever were one. Made from 100% sustainable silk (a nearly inherently sustainable fabric, although some companies use chemicals to yield greater results) with 50% soybean, 50% organic cotton braided banding, this versatile tank meets all of your new eco-resolutions. Nora Caliguri and Rachelyn Porter make up the design duo for Larsen Grey and are contributors to the new age of eco-friendly design with high aesthetic integrity. This Bellara Crop Braid Tank is a perfect year-round basic and comes in two fabulous colors, cement and royal. Admittedly, this tank will most likely only work with a high waisted number to match. If you're down with the whole look, check out our spread of some high waisted options below.
