My spiky bracelet is also from TOPSHOP. There was a huge sale when I bought it. That store also has quite a number of edgy items, So that is also the place to shop if you have an edgy style.
The meaning of an edgy style is someone who doesn't dress like any one else, wears DIY clothing, leather, studs and spikes.
I myself will always love studs, leather and spikes. Even if they may go out of style one day, I do not want to be like anyone else. DIY Counts as one of my hobbies.
There is currently a sale until Febuary 3, 2013 at TOPSHOP!
