If you think your kid is ready for a Halloween full of screams, then this Monsters Inc. Mike Wazowski costume for kids could be just the right thing for them to wear. Not only is it cute to look at but perfect for smaller sized children. Make sure that the worker’s hat is blue in color and not yellow like a construction worker’s! For this costume, it’s best to wear all green underneath it so that they are uniform in color from head to toe. Wear colors that match the costume exactly or are at least similar in color. Put on some cute monster shoes and your Mike Wazowski costume is all set!
