This Imposter costume idea takes a little more effort, but the end result is so fun. First, paint a container silver in the lower right corner and along the bottom, and paint an imperfect white rectangle in the opposite corner. Next, cut a cloud shape with fabric and put pillow fluff inside. Third, cut a small yellow circle out of fabric and put pillow fluff inside. The white and yellow fabric "pillows" make an egg hat. Then, put velcro strips inside your plain-coloured hoodie and on the container to make the mask. And lastly, hot glue the egg to the top of the hoodie.
