quick question about the wakefield raincoat

[splishsplosh]

i have spent ages looking for the thread on perfect raincoats and can't find it...

i remember the wakefield one was recommended, but does anyone know how the sizing comes up?

i'm an hourglassy type size 16, and wondered how generously it is sized, for extra layers when it's colder etc.

i need something soon as am fed up of getting soaked through on my 1.5hr round trip school run twice a day!
