Purchased the M (size 14), which is just perfect. Love this dress, as it is so versatile for beachwear/casual wear or over shorts and jeans. You can tie up the front or sides in a knot for a different look. The pattern is lovely, and the combination of blue is refreshing. A great dress to 'twist to pack' and pop over your swim attire when you need to. Being cotton, this is a blessing for the hot summer months. The melon colour is also gorgeous. Totally recommend these dresses.
