I have this dress for a special event we have coming up, I am a size 18. We will be outside for some time and I have a smart warm jacket and thick tights to wear. Can I wear boots with it? If so what length? I have chunky legs so would need a wide fit. Or if not what would you suggest? Need something comfy-ish for standing around. I’m not great at dressing smartly! Any advice gratefully received.
