Precisely. That's what really needles me - that we are led by the nose by advertising. Try finding a lifestyle/fashion mag without the words 'must have' on the front cover. I almost got caught up in it when the Fendi Spy was big - read all the hype and was convinced I really had to have one - then came to my senses and realised I didn't actually like the bag. Nonsense or what!
Now I buy my bags because I like them and certainly not because Victoria Beckham or the like is carrying them - that's enough to put me off.
Very well said sarajane!
