Peaky Blinders is the closest British TV has came to producing a show with the sartorial influence of Mad Men.
Ever since Cillian Murphy's glacial eyes first glared out from under that face-slashing flat cap in 2013, waistcoats, peak lapel long coats, and shirts with the top button firmly fastened have been regular staples on high streets once again.
But even more than the clothes, the Peaky Blinders effect can be seen in male grooming. "Cillian Murphy's undercut has been inspiring barbers since its inception in the 1930s," explains Simon Crawford of Johnny's Chop Shop. "Traditionally, it meant being shaved on the sides and keeping the weight on top."
"[T]he show barbers have given it a modern twist, making it one of the most popular hairstyles to hit our streets in years. This is done by keeping the basic style but combining [it] with a slick skin fade. It's sleek, stylish and very modern," he says.
To maintain the look, Simon recommends getting the sides cut every few weeks and styling it by adding texturizing spray over wet hair, then blow drying using a vent brush. "Finish with some clay to give texture and flow," he adds.
Now all you need is a flat cap and some chiseled cheekbones, and you're good to go.
