She's wearing a dress in a very similar style to what I would have chosen. 1950's tea dress style in grey lace. She's not having bridesmaids as it's very low key. So I don't want to look overdressed compared to her. I'm a curvy size 14/16. The wedding is in the Lake District in January so needs to be practical and warm. Any ideas? I was looking at Coast but they seem to have closed.
