All you have to do is find a pretty white dress and a wand and some
pretty make-up. That's it!
Thanks to Cameron for this fun idea!
To be a fairy: get a cute puffy colorful skirt, a pink/purple tank top, wings, and optionally a wand or tiara.
For a modern fairy: pink pants/Capri/ wink tank w/ heart/star on it...wings, pink visor with "fairy" painted on it...and lots of glitter!
Thanks to Sacce for these ideas!
