I'm in my fifties, size 8-10, hourglass figure. It will be a registry office wedding, either elopement or very small family group. I don't want to wear white. I would prefer to buy a second hand dress and I'm happy to spend several hundreds for the right dress. I look ridiculous in anything too frilly or flouncy so probably something quite understated but I would love the dress to have a wow factor. It will be a winter wedding. Any thoughts/ideas about where to look please?
