- The national day of Ireland, Saint Patrick’s Day is the celebration of the Irish Patron Saint (Paddy, for connoisseurs), which has become a beloved adopted although non-official holiday in American lore. March 17th is nowadays celebrated even among those of no Irish decent under the motto “be Irish for a day”. This is the green day, a color that represents the Irish, and is evocative of the lucky shamrock (a St. Patrick’s symbol). With it come lots of Irish folktales to the foreground, like the mythological creature male fairy, the Leprechaun. Wonder Costumes invites you to celebrate the Irish feast!
