To wear this top, simply put it on like any other long - sleeve top. It looks great on its own or layered under a jacket or cardigan. When it comes to sizing, keep in mind that it runs a little long, so you might want to consider that when choosing your size. For maintenance, it's best to follow the care instructions on the label. Usually, a gentle machine wash in cold water and tumble dry on low should do the trick. Avoid using harsh detergents or bleach as they could damage the fabric or fade the colors. And if you notice any loose threads from the elbow patches, just snip them off carefully with scissors.
