Using this Ant-Man 3 adult costume is super easy. First, put on the all - in - one digital printed jersey. It's designed to fit you comfortably, so just slip it on like a regular piece of clothing. Then, put on the Ant - Man mask. Adjust it to fit your face properly so you can see clearly and have a great cosplay experience. When it comes to maintenance, after each use, gently spot - clean the jersey and mask with a damp cloth. Don't use harsh chemicals as they might damage the digital print. Store the costume in a cool, dry place to keep it in good condition. Avoid folding it too tightly for long periods, as it may cause creases on the print. Also, be careful when moving around in the costume to prevent any rips or tears. Have fun and be the hero you were born to be!
