has anyone shopped here? tell me all about it...

Forever21 has just opened in London. I've not been to the store yet, but by all reports it's going to be taking on the likes of H&M for bargain fashion finds. The jeans look pretty decent on their website, but has anyone tried them on? They are definately cheap. Maybe not a good sign... Anyway it's a Californian company, selling Korean trends. Interesting newcomer to the UK fast retailing race!?
