I took some time to think about this from different angles... This is a really enlightening and very worthwhile discussion - thanks for being brave enough to post it! Since everything has pretty much been addressed, I'm just going to attempt a breakdown of the ways I saw to consider this issue...
First angle: Is this particular Burberry coat worth it? I'd say no. I covet a Burberry coat myself, and I'm happy to admit I've fallen wholesale for their marketing and new edgy yet timeless image. Everyone else has already pointed out some of the issues with this one - beige, silk, etc.
Second angle: Should you spend this much on any item of clothing? That is a hugely personal decision, based on many factors, again already listed by quicker members than me! "Is it worth it?" and "Can I afford it?" are two totally different questions. And of course, "Do I need it?"
Third angle: Will any item stand the test of decades? Here you'd have to consider not only fashion changing, but your own tastes and size and needs possibly changing as well.
Fourth angle: This is an unspoken values-laden issue. To some people it will be abhorrent to spend X amount of money on clothes. Lots of reasons play in - upbringing, personality, beliefs about materialism, religion, etc. Everyone has that X factor - for some it's $5, others $50, others $500. I've become a bit spendy recently, but 5 years ago you wouldn't have caught me outside a thrift store, unless it was e-bay or consignment.
When I first came here, I was stunned at how much some members were willing or able to spend on a single item. Now I'm probably closer to being one of that group. I've had to learn to step away from the whole "Could *I* afford that?" or "How is she able to buy so much?" and consider only the question being asked. It's kind of freeing, actually.
Anyway, I appreciate this discussion tremendously and if you do end up with a Burberry, I hope you don't mind if I live vicariously through you.
