"Quirky, playful, affirming fun!"-Kirkus

Four-year-old Leah loved being a pirate for Halloween. She never considered being a princess or a fairy, no matter what her friends said.
But once Halloween has come and gone, Leah misses so many things about her costume. She misses her sword. She misses saying "Arrrr!" But most of all, she misses her silly mustache.
But Leah knows that it doesn't have to be Halloween to play dress up. She can wear a mustache whenever she wants! She can wear one while she's watching a movie, or riding her bike, or playing her favourite game.
So when Leah's birthday finally arrives, she knows exactly what she wants to do: have a party where everyone must wear a mustache! At Leah's mustache party, everyone gets in on the dress-up fun, even Grandma!
