I don't see what the big deal is. If you can't afford it or aren't into purses, don't buy it.
This. A major pet peeve of mine is "reverse snobbery". Come on, folks, being judgmental is always wrong!
Everyone agrees that "rich people" shouldn't look down on those who spend less. So why do those who spend less think it's okay to look down on "rich people" for spending more? If it's not nice in one direction, it's not nice in the other... Seriously, think about how incredibly pissed we'd all be if someone posted a $30 diaper bag and said, "Can you believe people seriously would buy this ugly tacky thing? Why not just set your $30 on fire? Next time maybe try buying something that actually lasts for years instead of imported poly that will rip in a month." Ouch. Not cool, either way!
And, as a sidenote to those that mentioned it... A celebrity would be extremely unlikely to carry this particular bag. It's not a new style or even a new fabric this season. (I like Kate Spade fine but she isn't The One Thing at the moment.) Also, a celebrity would not have to pay for it.
If you want to see expensive bags, try Givenchy, Celine, Lanvin... Yum.
