Agyness DeynThe light, sunny days that were summer are a thing of the past.

And with the gloomy autumnal days in full swing, it's time for a new look.

To show her switch to the dark side, Agyness Deyn has ditched her soft blonde locks for a more severe mop.

The British model has transformed herself thanks to her new hair colour, but we're unconvinced as to whether it's a good move.

Rather than opting for a few shades darker than her light locks, Agyness has gone for an extreme jet-black crop.

A daring choice, if you ask us, and one which we're not sure that even this beauty can pull off.

It also doesn't help that she has a rather dodgy cut, more Worzel Gummidge than Vidal Sassoon.
