1. Fortune Teller - Dress up in a flowy skirt, a sparkly top, and a shawl, complete the look with a crystal ball, tarot cards, and lots of glitter.

3. Medusa - Snake headpiece, green make-up, dress up in a white or grey gown, and wrap rubber snakes around yourself.

4. The Night Sky - Dress up in black with small LED lights as stars, use white or silver fabric to create a crescent moon on your forehead, and accessorize with star jewelry.

5. Sugar Skull - White base make-up with detailed black lines, use colorful paint to add intricate designs. Complete the look with flowers in your hair.

6. Space Girl - Dress up in a silver jumpsuit, and add lots of glitter and futuristic accessories such as metallic gloves, boots, and sunglasses.

7. Steampunk Inventor - Create a look using a corset, boots, goggles, and other vintage-inspired pieces, and add some creativity with gears and gadgets.

8. The Incredibles - Go with your friends or family and dress up as Mr. and Mrs. Incredible, Violet, Dash, and Jack-Jack.

9. Cleopatra - Wear a white or gold gown, a black bob wig, and eyeliner that goes out towards your ears, and add accessories such as gold jewelry, an ornate headpiece, and armbands.

10. Ghost - The classic sheet ghost costume but with a modern twist, make a colorful sheet and use LED lights inside to glow. Accessorize with a pumpkin trick-or-treat bucket.
