To use this awesome zombie schoolboy costume, simply put on the grey trousers first. Then, slip into the jacket with the attached blood - stained shirt. Finish off the look by tying the zombie schoolboy tie. For Halloween parties or haunted houses, you can add some fake blood or dirt to make it look even more realistic. Remember, this is an adult costume and not a toy. Keep it far away from fire to avoid any danger. When it comes to maintenance, since it's dry clean only, take it to a professional cleaner. Don't try to wash it at home as it might damage the tattered look and the blood - stain effect.
