The demise of fashion?

Hi everyone,
This is my first post on here, so firstly i'd like to say hello to you all! I'm a fashion design student based in London and wanted to find somewhere to discuss my latest fashion gripes and new loves.
One things that i wondering whether it is a good thing or not, is the introduction of celebrity fashion lines or general brands associated with a celebrity. We've all seen Victoria Beckhams new little black dress range, which i think is amazing, and Gwen Stefani's LAMB. But where does it stop, or should it even have to?? Perhaps it gives us the consumer more choice, which can only be a god thing in my book...i think?

So from Kate Moss Topshop range to the UK's only Estonian export, singer Hannah (Ild) producing a range of gloves. Are we at a great time in fashion where the consumer has more choice or are we being overloaded by celebrity nonsense?
