Seven layers of white nylon netting gathered at the neck with seam binding make an apparition as light as air.

Costume How-To
Measure the wearer's height, double it, and cut about 7 lengths (depending on desired degree of transparency) of white tulle to that measurement. Tulle comes in 54-inch and 72-inch standard widths; we used 108-inch width from a specialty store. Stack lengths of tulle; mark center point of one long edge to indicate top of hood. Measure from shoulder to shoulder over head of wearer, add 3 inches, and divide by 2.

Measure that distance from center point on tulle to make an arc. Mark arc with pins at 3- to 4-inch intervals. For the tie, thread a yarn needle with 3 yards of white yarn, ribbon, or seam binding (we used black for illustration). Weave through all layers along arc, leaving ends for ties. To finish, shred top 2 layers of cape, tumble briefly in a hot dryer, or apply glow-in-the-dark paint.
