Congratulations Eljean! Ask for thermal underwear, fleece coat and never go out with wet hair.
I live in Bath and I'm fine with the weather. Visited Leicester for a wedding two weeks ago and it was effing cold! Two layers of clothing was definitely not enough there. Been sick ever since.
Oh, and if you're buying one off the ebay stores, make sure you check out the name. Bought several tights and vests and got a telling off. Why? My fiance received "Thanks for buying fantasy tights from madamefantasy!" in his work email. Webmaster and other colleagues teased him for that. My bad.
