Coral dress

I bought it from a mannequin it was the last one in the store. They sold it as is. I am a size 4US and fits me ok, the tag on it says 8. I ended up wearing a different dress for the event, because of the color ... So this one never been worn. In the last picture the 2 pieces were given to me as extra. However the one on the left it does fit as a belt - see first picture. Feel free to ask questions.
