We love the cotton gauze from It Is Well.  It's soft, light and has a lovely drape.  It's machine washable and therefore user-friendly.  The reversible gauze top is a light/boxy top that is relaxed without feeling too oversized.  It can be worn as a v-neck or round neck.  100% cotton, machine wash gentle and tumble dry low.
