Zipper on the back. Maintenance: handwash. Virgin wool dress is more exclusive. We use virgin wool materials for our dresses, which do not make the skin itchy. If you want a material that is natural but does not wrinkle, then virgin wool is the best choice. Woollen fabric breath well and does not make you sweat. But if you do sweat due to hot weather then wool absorbs this moisture and leaves the skin feeling dry. Elastane makes the material slightly stretchy and therefore more comfortable to wear.
