help!!!!!!!!!!!!!!

i want to be gyaru....... but i have a few problems

i live in the uk and am in my early teens. from experience, it's not very acceptable to dress 'alternatively' here. when i say 'experience' i literally mean a leather jacket, band t-shirt and jeans with eyeliner. my other experience is with wearing all black. seriously. it's also soo common for women to have a 'trashy' style and if i got the gyaru look wrong, i might actually look like that. i am terrified to try it but soooo excited about the idea. PLEASE HELP!
