To wear this Nissi shirt, simply put it on like any regular shirt. It's a great piece for casual outings or can be dressed up a bit. As it has a few small marks on the front, don't worry too much about getting it a little dirty during normal use. When it comes to maintenance, you can machine - wash it in cold water with a mild detergent. Just be gentle to keep the color vivid. And remember, since it's a non - returnable sample, take good care of it so you can enjoy wearing it for a long time.
