Rowena Ravenclaw from Harry Potter
There is no official actress for Rowena Ravenclaw as the founder died long before Harry Potter attended Hogwarts. And while there are descriptions in the book, cosplaying as Rowena still leaves lots of room for personal interpretation. The one thing you don’t want to forget, however, is her diadem.
For this version you’ll need a long auburn wig, a blue gown, matching blue slippers, a wand, and a leather journal with a blue stone. An eagle necklace rounds out the bewitching look.
