Whipping your long hair into a short bob? It sounds incongruous, but it's actually doable using a few bobby pins. This way, whether you're dressing up as a flapper for Halloween or a murder mystery party, you won't have to chop off your Rapunzel locks just to get the flapper look right.
This is how to achieve a 1920's inspired bob even with long hair! Your hair doesn't have to be as long as mine, for this to work, just longer than a bob. It's fairly simple and quick, the perfect touch to any Halloween costume!
