In England in the 20s, the Peaky Blinders were very fashionable, especially their haircuts, which have started to come back into fashion little by little almost 100 years later. To look like Thomas Shelby, Arthur Shelby or Michael Gray, here are a few tips that you might find useful.If you want an undercut like Thomas Shelby, ask your barber for a short back and sides (about a 1-2) but keep it long on top with length in the fringe so you can sweep it across. If you don’t want to spend any money, you can always do it yourself at home. Put your trimmer on 1 or 2 and shave your sides and the back of your head. On top, leave about 5 or 7 centimetres of length for the best result.If you want Arthur Shelby’s hairstyle, ask your barber for a ‘disconnected undercut’ by telling them that you want that slicked back look. To achieve this yourself at home, nothing could be simpler. Just like for Thomas Shelby’s haircut, put your trimmer on 1 or 2 and shave right down the sides and the back of your head and keep as much length on top as possible.Finally, if you want the classy Michael Gray hairstyle, you should ask your hairdresser for a classic 20s style side parting, telling them that you don’t want the sides to be shaved, but cut with scissors for more elegance and precision. However, if you want to recreate this look at home, you need a bit more technique: keeping your length on top, progressively thin out the sides and back of your head. And finally, try to clean up the hair around your ears to give your style a nice finish.If you're after the clothes to complete the effect, then look no further than David Beckham's Peaky Blinders collection.
