You could dress as E.T., elf, Elvis Presley or an Eskimo. They begin with the letter e.

If the theme for the party is a sleepover one then you'd obviously wear your pj's or you can wear a wanzee. If the theme is popstars then you can dress up as your favourite singer for example, Selena Gomez, Rihanna, Taylor Swift, Cheryl Cole, etc. If it's a fancy dress party, you can wear a big, pretty gown, or you can wear a really nice dress. I hope this answers your question thanks.
It depends on what kind of party it is. If it is a pajama party, wear your pajamas, if its is a pool party, you can wear your swimsuit. Halloween parties? Wear you r scariest Halloween costume. ^_^Depends on the theme once you find out the theme Google costume ideas or look on Pinterest
