Beautiful but runs small
This is one of the best quality dresses I've ever tried on from Lulu, and I've tried a lot. The shape is beautiful and so flattering. But in most of their dresses I am an XS, though in this one I would get a S if it was still available since it is quite tight around the waist and tummy. It's still wearable and I'm going to keep it since it's so beautiful, but I would definitely recommend sizing up if you can.
