You wise buddahs sorted me out for a summer wedding earlier in the year and now I have a winter wedding conundrum. The wedding is being held mid December in an unheated church and then in a barn. We have been told to wrap up. A friend has loaned me a floor length black coat with black (fake) fur trim at the collar and cuffs (which I need to get a belt for to cinch it in as it's too big for me). I have zero clue about what to wear underneath it. Would anyone have any ideas please? I am size 10 and need to have my decolletage area covered as it's scrawny - photos attached so you can see what we're working with. To complicate matters further I am on a budget: £50 tops. Thank you.
