To use this Zia Top, simply put it on like you would any other top. It's great for casual outings or a night out. When it comes to maintenance, it's best to follow the care instructions on the label. Usually, a gentle machine wash or hand wash in cold water is a good idea. Hang it to dry to keep its shape. As for the small black thread on the front, don't worry about it. It doesn't affect the overall look or wear of the top. Just enjoy wearing this one - of - a - kind piece!
