I bought this dress for a wedding a while ago and wore it only once. There's a photo of me wearing it in the sixth image (at the time, I was 158cm tall and weighed 54kg). I was four months pregnant with my second child then, but it was fine. It's a Zara size S, so it might be closer to S-M. The collar is raw-edged. It's a very glamorous dress that fits the body perfectly. Feel free to ask any questions in the comments.
