his hairstyle is one that I do when I want an up do, but not a simple pony tail. It’s really simple, I copied it off a style I saw at fashion week last year and believe me- if I can do it you can too!
All you do is put you hair up in a pony tail, leave a section at the front out and braid/plait your pony tail down towards your forehead. Then just pin in place. If you have long hair like I do then you can just pin the plait back, wrap it around your head- anything really!
