How do I make a cheap DIY Moonlight costume?

Wear a dark blue or black outfit you already own, cut a crescent moon out of cardboard, wrap it in aluminum foil, and attach it to a headband. Add silver glitter to your face for an instant cosmic look.

How do I make the costume actually glow?

Weave battery-operated, cool-white LED copper wire fairy lights through a sheer outer layer of your clothing, such as a tulle skirt or organza cape.

What should I wear under the sheer star cape?

A solid, dark-colored base layer like a black or navy blue slip dress, bodysuit, or matching top and leggings works best to let the silver stars stand out.
