Before i bought the dress, i was skeptical because of the reviews. all did say it runs small so i bought a M instead of my usual S. I just got it today and it is absolutely gorgeous. I love how it fit and its just beautiful. Really makes me look SNATCHED. the top has a corset type with the bars inside which adds more structure, i really liked this. the bottom was also very gorgeous. the only thing was the straps. The straps were a tad bit longer but thats fine i can easily fix it. other than that, the design is so cute and it fits really well. It is mid open back and the top is a straight top.
