Here are some ideas
You and two friends could be the pink ladies from Grease.
You could be a dead cheerleader i's a lot cooler.
You could be a movie star and a friend could be your agent. Another friend could be the Paparazzi.
Being a bumble bee is another idea.
Other ideas are:
a witch
an animal, like a cat or a penguin
If you want to be unique, do not go as a witch, wizard, spider, ghost or devil. They are too common.
Some cool costumes for two people are:
horse head; horse "bottom"
a chicken and an egg
angel and devil
prisoner and policemen
Buy wings at target. Sew them on to a shirt or jacket. Put on the shirt or jacket and you have your costume.
Group Ideas:
The most popular and common Halloween characters for girls are princesses. Every little girl dreams to be a Disney princess, therefore they go with being Ariel or Cinderella, as well as all the other Disney princesses.
There are plenty of fun and creative ideas for young girls' Halloween costumes. Here are some of the most popular ones that your daughter is sure to love:
All of these costumes are perfect for young girls, and they are sure to be a hit at any Halloween party!
hmm....
Little Red Riding Hood (though that one has been used much too often); Batman, Superman, WonderWoman (any superheroe, though you can't just make the costume-you have to buy the ENTIRE thing, including the fake padding-muscles.... and no girl would want those...); and elf (exactly what I'm gonna be!! what you do-put tape around your pinched ears to make pointy elf ones! it doesn't hurt at all unless you get hair in it...); The Thief Lord (refer to Cornelia Funke's book "The Thief Lord", or simply type it into Google Images...); Hobit; Goblin; Royal Troll; etc; etc; etc... for more ideas...
The answer before was very rude, I bet they aren't as pretty as her. There isn't, but you can easily make one with a bathing suit and surf shirt! You can also get great priced surfboards on craigslist for under $30!
Some ideas:
Her favorite animal
Her favorite pop star
A group costume with her friends
Her favorite literary character
Her favorite movie character
Her ideal future career
A classic Halloween costume that's not too gory (Mummy, vampire, werewolf, witch)
Her favorite food
A punny costume
You can make an easy homemade one like I am. I tried it before it was fun!
1: beard, grow one if possible, if not costume shop
2: temporary gray hair dye
3: hat
3:goodwill store. Just watch a few episodes Nd figure out what looks right
4: work boots
5:whatever props you want to help sell the costume, I'd suggest a fake shotgun and/or a book on the occult

you could probably find them on ebay or a special website for halloween costumes if you cant find them there then i'm sorry i dont think i can help you with that but maybe you could just look for shoes that look similar to the ones the charachter your dressing as wears e.g if you dressing as draculaura you could just wear high heeled pink boots or you could wear some wedged black sandals like lagoonas.
hope i helped :P enjoy halloween.
Well, I'm going to be a mime for Halloween, and I thought it was gonna be really good for the costume if you wear a beret or a top hat. Black of course. I hoped this helped!
With paper or yarn or cut a shirt that doesn't fit you anymore
I would say something like a devil or a cute angel.
just don't be to obvious or look to grown up for your age
