.80 pounds; 129 usd although I think for Americans, it's much more expensive for you because I noticed when I was in NY the prices at topshop were jacked up way more even after foreign exchange. So my guess is around 160 ordering from the American site or buying in store.
MissyG, I am wondering this as well. I can't believe some people are asking like 300 bucks for them! Crazy.
How far back did they come out?

I might be wrong but I think Topshop will probably restock them again. I am looking forward to the silver colour ones and I expect they will sell out just as quickly
