To use this Michael Myers costume, first put on the blue jumpsuit. Make sure all the buttons and zippers are fastened properly. Then, put on the latex mask. You can hold the included knife to complete the look. Remember, this costume is for adults only, so keep it away from children. Since the dyes may not be colourfast, avoid getting it wet with coloured liquids. Always keep it away from fire to prevent any accidents. If you have a latex allergy, be careful when handling the mask. For maintenance, take it to a professional dry - cleaner. This will help keep the costume looking great for many Halloweens to come.
