Ohhh, yes, Steve! If you have the money, you can have pretty much any item worn by our combat airmen in WWII, including those nice jackets!
There are a few "reenactors" on this board, IIRC, and they can fill you in in much greater detail than I can about purchasing a jacket style - and from where - but the jacket Gabby is wearing looks to be the B-10. It was lighter and more flexible than the A-2 leather jacket, though the leather can't be beat for looks! The B-15 is very similar in appearance, but with the B-15 the jacket zipper is "offset" (not centered on the chest) an inch or so to the wearer's right, IIRC.
These days, commercially, the faithfulness to the original specs varies from an almost exact duplicate of the WWII issue (including, on some models, the lack of pockets where you might like them today) to something that 'appears' sorta-similar, and the cost varies proportionally. One thing to keep in mind is that the WWII jackets were each manufactured by a virtual rainbow of different contractors, and each had their own "signature" differences, be it collar style, zipper size, etc., etc. That goes for all the jackets, but you can find all the info your heart desires via Mr. Google if you really want to nail down a specific, exact flavor.
While researching my last A-2 purchase, I found that there are even plenty of 'geek' sites that are actually very informative and full of neat historical data about the jackets, even telling you to get a size smaller than you normally wear for that WWII "fitted look" - I agree, since few pics I have seen show the guys back then wearing jackets that were too big. What they don't remind you of is that those skinny guys in the WWII pics were all in their early 20s, and could get away with tight-fitting jackets -
and still move!
From my experience of buying several jackets over the years, I'd say spend a good bit of time researching them on the 'net, and see what the 'jacket geeks' have to say about the ones offered commercially. Sometimes you can find a great place you never heard of that'll give you a superb product for a decent price.
Here's one site that shows the B-10:
