Here in Englad, Aubin and Wills (with Jack Wills, which is basically another line from the same company) is strongly associated with insecure middle-class university students trying to look like country gentry. In fact, the Jack Wills slogan is "Outfitters to the Gentry". It's all a bit pathetic, but I guess taken out the context of the class neuroses of the UK, this might not matter. Some of the stuff is quite stylish, but universally WAY overpriced, and often has logos all over it.
Jack Wills is almost all made in China (though often using British cloth in the case of wool products, a fact they trumpet loudly), but I'm not sure about Aubin. If your jacket IS made in the UK, this information will be written somewhere in huge letters.
