Roaring 20's Flapper Girl Retro Invitations. A great retro party invitation taking it all the way back to the 1920's when the flapper girl was the style. These invitations feature a flapper girl in her finest with flowing dress, a boa around her shoulders, feather headband and holding a martini glass. This invitation is period correct and will be oh so fun for that flapper party where your guest dress up in their gangster suites and flapper dresses!
