She has the best coats doesn't she?

The only help I can give is that I've read on various boards that women have found the black leather jacket she's been wearing recently at the GAP.

Wish I could be more help but I've looked at various clothes shops online and haven't had much luck finding any of them.

I've found a jacket similar to this one in Old Navy a month ago. I'm not sure off hand if it's still there.

She wears a Burberry cashmere/wool trench during the first season (black coat.) I only notice because I own the same one.

Well I guess now we know what Det. Beckett spends her money on; clothes. From the Herve Leger dresses to the Burberry coats.

I am always so interested to see the clothes characters are wearing in my favorite TV shows b/c generally, they are always designer. Even the hideous clothing Betty wears on Ugly Better is designer, just thrown together in a horrific way.
I admittedly love seeing what Kate Beckett is wearing every week. And my God, I only wish I could look as amazing as Stana in that Herve Leger dress. So not fair!:

By my count this season we are up to 25 different jackets and coats with at least 9 different leather jackets. The jacket on the show last night with the unusual collar/lapels is by Armani i think – or it's a knock off of an Armani design i saw recently.

Castle made a comment during the pilot when he was telling Kate her 'story' when they were looking at fan mail – about her being 'Manhattan and that means money' – well it's got to be true. The quick glimpses we've seen of her apartment belong to a place that would cost lots more than they pay cops in NYC and her wardrobe is similarly (a) extensive and (b) often high end. But then again, this is fiction after all.

Add another jacket to the expensive column.  I remember noticing the dark blue vest/jacket that KB had on in Suicide Squeeze as i couldn't figure out whether it was blue or black or a jacket or vest. (Thank god for PVRs so you can rewind and watch things a zillion times & zoom in on things.) Wandering through a high end boutique today and guess what i ran across?  Turns out it is a jacket with a leather front, fabric back and sleeves by Ralph Lauren Black Label – list price just under $2,000.  If the clips are right for the Tick Tick Tick Boom episodes – then that's some mega-$$$ worth of wardrobe that's getting blown to kingdom come.
