I'm going to my sister's wedding in a couple of weeks. It is a very, very small 'do' - dh and kids are not coming. The wedding is in the registry office and then meal afterwards at lovely gastro pub. The reason for all this is that my bil has been diagnosed with aggressive lung cancer. It's terminal.
Obviously the day is going to be hugely emotional and I don't need anything complex to think about. My sis is wearing trousers and a light coloured jacket with nice hair and flowers and special shoes 
I have brand new wide black trousers which I was thinking about wearing with new black ankle boots (which I will need to find). I need a top and probably a scarf because for warmth I think I will need to wear my long black jacket. Obviously I don't want to look like I'm going to a funeral but I can't really buy a new coat as well
The only other thing I have to wear is a navy pinstriped suit but I don't want to wear that as it is not all that warm, is very plain and the last time I saw my sis I was wearing it to attend our cousin's wife's funeral (yes - it has been an awful year!)
What do you think? What would you wear/
