I've been invited to a 40th birthday party this month. In the UK, at friend's parents house, evening, can be smart or not. I'm thinking of wearing this dress. Is it ok for Winter? What shoes etc? This is my first smart non-wedding event in a while, so I'm unsure. Sorry for lack of photo of me in it but it does suit me. I'm 5ft10, size 10, light olive skin, straight medium brown hair in a bob.
