long skirt fitted jacket suit - any suggestions where to get such a thing?

[time4tea]

Hello

I'm a size 14/16 with great norks, reasonable waist, big bum and very chunky legs. Usually keep to long panelled skirts and trousers. I need a suit for work, with a long panelled skirt and fitted jacket. Need quite subtle, serious look, nothing flash.

Any suggestions where to get such a thing, MN fashionistas?

I have a lovely one from Jigsaw which makes me feel v. thin. Expensive though but haven't found the same sort of combination much cheaper than Jigsaw/ Whistles.
