Witch

• Pop culture interpretations of witches vary from benevolent, pretty young witches to evil, old hags full of warts and crooked noses. Whatever their nature and appearance, a witch almost always wears a black dress. The classic witch costume consists of a long black dress with long sleeves. Often, a witch wears a tall hat with a pointed tip and a round bring, displays long hair and carries a broomstick. Deck out a witch costume by carrying around the household broom. Other accessories include purple, black or striped tights and brightly colored or dark jewelry.
  
  

Cat

• Typically, a simple cat costume consists of a black leotard and tights or a long-sleeved black shirt and long black pants. However, a tight black dress converts to a cat costume with the addition of cat ears and a cat's tail. Typically, cat ears consist of a black headband with two triangles on top. A tail consists of a long, thick piece of thread or fabric and attaches to a dress with a safety pin. You can find cat costume accessories at costume shops and party supply stores. You can create a cat headband or tail with black fabric and glue.
  
  

Holly Golightly

• The main character of the film "Breakfast at Tiffany's," Holly Golightly -- portrayed by style icon Audrey Hepburn -- popularized the little black dress. The Holly Golightly costume best matches a classy, formal black dress with no sleeves and a high neckline. To turn a simple black dress into a Holly Golightly costume, add a thick pearl necklace, over-sized sunglasses and long, white gloves. If possible, wear your hair in a stylish bun or up-do.
  
  

Dark Fairy

• A dark fairy costume matches most black dresses but pairs especially well with a feminine or frilly dress. A fairy costume typically consists of a short dress, flat shoes and fairy wings. To create fairy wings, cut a butterfly wing shape out of cardboard and glue the wings to the back of your dress. If possible, pair your dress with store bought wings. Store-bought wings attach to your shoulders and don't require the permanent alteration of a dress. Possible dark fairy costume accessories include wands, choker-style necklaces and patterned or fishnet tights.
  
  

Pop Star

• Because pop stars wear a wide variety of different costumes, many styles of black dresses match the costume of a pop idol. Typically, female singers wear skin-tight dresses with low-cut necklines and short skirts. However, there is no standard. Pair a club-style black dress with high-heeled shoes, bright jewelry and a blond wig to create a pop-star costume. To add extra authenticity to the costume, carry a microphone or wear a microphone headset.
