birth til 10 years old - bland, no real style. hair was boring, curly and frizzy. No make up.
11 til 13 - what can only be described as "emo trying to be goth". Hair was badly straightened. very very very bad eyeliner.
13-14 - metalhead. baggy jeans, massive tshirts, the lot. Long, grudge style hair. Really quite embarassing. either no eyeliner at all, or loads.
14 til just before i turned 15 - scene. Got loads of layers in my hair. Dyed my hair light brown, then dark brown, then purple-black. Couldn't get rid of it, had incredible roots so cut all my hair to chin length & spiked it out at the sides. Started wearing foundation & stuff + got better at eyeliner.
15 til now - a combination of indie/scene/metalhead. Depending on my mood. Dress much older now. Skinny jeans, heels, tshirts and shirts, etc. Hair is long, layered and straightened all the time. Stopped wearing foundation anywhere other than my eyes, greatly reduced the amount of eyeliner I wear.
Even within those, I changed a lot. I decided to be quite vague to save you guys having to read a wall of text.
I quite like the way I am now.
