Lizzie McGuire: Wear a tight tank top and pajama bottoms and flip flops. Dye your hair blonde if it isn't naturally. Put on some makeup, there you ready to go!
Thanks to Hi-it's-me! for this fun idea!
Another Idea....
You need to wear blue flare pants with a pink tanktop (shortsleeves).
Then you need orange sandals. Also you can get a short haired blond wig or if you have blonde hair get bangs. Then your Lizzie Mcguire.
Thanks to Melanie for this idea.
