To wear this Zalla dress, simply button it up from the front and tie the self - tie waist to get the best fit. You can wear it on a casual day out with flats or dress it up for a more formal event with heels. When it comes to cleaning, follow the care instructions on the label. Usually, it's best to machine - wash it in cold water on a gentle cycle. Avoid using harsh detergents as they might damage the cotton fabric. Hang it to dry to keep its shape. And if it gets wrinkled, you can use a low - heat iron to smooth it out.
