top bollocks
ahem...anyway, IMO Gore sizing has gone tits up, if you'll pardon the pun. They always used to fit me perfectly and I've not changed size in 10 years!
A couple of years ago I bought a Gore ladies goretex waterproof, in a medium. I'm a size 12 with bigger-than-average boobs and muscular shoulders. It fits perfectly - nice and snug, with room for a couple of layers underneath.
In fact, this is a picture of me in my nice Gore jacket. I'm a bit cold, even though I have 4 layers on under it! But you see what I mean about the fit.

Last summer I bought some Gore goretex overtrousers over the internet thinking 'these will be great because Gore always fits me perfectly.' They were a size 12 too. So I got them, and, first of all they're really low cut and so pull across the front, which is v uncomfortable when cycling - they're overtrousers not fashionable pants! Then they're really tight around the arse, and the legs are about 4 inches too long. They were made for someone who is more like a size 10 with 34" inseam (so Buggi, they'd fit you fine!). Every single pair of trousers I own is a size 12, and I've not had a problem with Gore until the last 12 months.
I use the trousers for walking in now, and they're fine for that, but they simply don't work as cycling overtrousers because of the fit.
