The hat should be as light in color as possible, or people will be able to see it through the bed sheet that will be draped over your head.

The costume should drag just a little to create a floating effect, but not so much that the person wearing it trips.

Pin the sheet around the hat; you’ll need to use about three or four more pins. If you don’t want the black dot on the top of the head to be so noticeable, you can flip the sheet over. You should still be able to see where the mark on the top of the head is, but it will be less visible to onlookers. You can also just cover the mark with white-out. Or, use a fabric marker pencil that fades (invisible fabric markers).

You can also put the makeup on the person’s neck, since it will be visible.
