here’s a few original ideas that are either cute, funny, or just fun (some may not sound appealing but you can make anything cute/funny if you wear it right)-
-nerds(suspenders, glasses, calculator)
-roller derby girls(you get to wear roller skates! like the old fashioned ones with four wheels, and high knee socks)
-quarter back(tape a quarter to your back)
-highlighters(each of your friends goes all out wearing a different neon color ie: pink,orange,yellow)
-gangstaa(baggy pants, over sized t-shirt, hat)
-comfy- "as in comfortable"(wear really comfy clothes ie:uggs,sweats,sweatshirt/sweater and when people ask you what you are, you say, "i am comfy" they will laugh)
-lindsey lohan(dress really messily<–idk if thats a word, huge sunglasses or dark circles around your eyes, carry a diet coke)
-winnie the pooh cast- each one of your friends could be a character from winnie the pooh ie: pooh bear, tigger, eyore, piglet, winnie, the owl)
-a meriacci band(mexcan band, sombraros, mustaches, black wigs, each person carries a different instrument ie:ucalele(guitars are too big),maracas,drum)
-lady gaga(just wear something totally crazy and people will believe it!)
–just make sure its classy and it’ll be great!
ideas that people ALWAYS do and arent very original:
-waldo(where’s waldo)
-sports fan/player
-sailor
-farie
-little girl
HAVE FUNN AND BE CREATIVE!

My only suggestion is to cover up. Girls seem to use Halloween as an excuse to go outside half dressed when they wouldn’t do that any other day. I don’t think that is cute at all.

Go as a baby..

You can get the footed pajamas that has the button flap in the back, you can get diapers from http://www.bambinodiapers.com. Leave the flap open on the footed jammies so everyone can see your diapers. Have a baby bottle filled with juice. Have a pacifier tied to a ribbon on one end and the other end fasten the pacifier/ribbon to your jammies with a diaper pin. And lastly put your hair in pigtails. Fun costume and not that expensive to make.
