I am going to be a bridesmaid this autumn and will be wearing this this dress. I think I will need a cardigan or similar otherwise I am going to freeze. The wedding is rural rather than in the city, so dressy but not really smart and bride has no specifications although I think she would prefer it if I didn't wear black. I would prefer it if it was something I could wear again this autumn/ winter and not too expensive. Any thoughts? I was thinking about a dark purple fitted cardigan? My knowledge of what's in the shops is useless.
