Another Britspeak need some help WAS Re: Peeling Sprouts?

[M.Clifford]

HI all,

On the main list, someone asked for an explanation of "after a
fashion". Since I am Aussie, not British exactly, I couldn't give an
origin for the saying, but I did my best to explain the meaning. 

Who could help with that, does anyone know the origin of after a
fashion? I am guessing it's to do with "fad" as in, it was over faster
than a fad (fashion trend for those who don't get that) or something.

If I am making any sense, I hope I am..
