To wear the Ava black dress, simply put it on over your head. It's a one - piece wonder that's easy to slip into. For a casual look, wear it with flats and some dainty jewelry. If you're going out at night, add heels and a statement necklace. When it comes to maintenance, check the care label on the dress. Usually, it can be machine - washed on a gentle cycle with cold water. Hang it to dry to keep its shape. Avoid using harsh detergents as they can damage the fabric. And always store it in a cool, dry place to prevent any mildew or damage.
