If you've been back more than once to try it on, then you've been bitten.
Nothing else will do. If you compromise, you will always be haunted by the jacket that "got away".
Find the best price and buy the one you dream of. Save yourself the pain.
For Real McCoy's these days, you would want to get them off the rack. Their QC is getting worse and worse.+1 If you're willing to throw that sort of money at a jacket, go with GW or an Aero and luxuriate in the knowledge of the craftsmanship that's gone into something made just for you, rather than off-the-rack. If you're fixed on getting a similar A-1, Aero's current seal Vicenza is stunning, the equal to Shinki, and they also stock olive green knits.
That's a beauty, Devilish! Is that the more recent cape from GW? (Dig the hat, too.)Here's my GW in a specially 'washed' cape skin. No olive knits, I know, but it drapes nicely.
