This dress isn’t perfect but still very wearable with imperfections not noticeable when on. (These dresses are expensive but so delicate that they are bound to get imperfections even with one wear.) It has a few sequins missing, which I have photographed close up in last pictures. It also has one dot on the silk, which appears to be pen but is small and gets lost in the pattern of the dress.
You could probably replace the few missing sequins quite easily but it is still a show-stopper without. Made iconic by celebrities such as Erin Andrews - please google the name of the dress for stock images.
