Looks really good! The comment were talking about how short the dress was so I was worried, but when it came in, (and on Christmas day at that!) I was pleaseantly surprised to see that it isn't too short. Don't get me wrong, it's short, but when you bend over it still covers up your ass so it's not insanely short.
M is big for me (not fit to the waist), 153cm/50 kg; but I’d not recommend S, because S will be too short
