This is a ISSA London silk jersey dress with a beautiful key hole detail with a tie on the back. It features a signature ISSA print from a few seasons back, and you will be the only girl wearing this dress. Unfortunately, I had removed the tag after I bought it, so I don't have it. But it is a size 4/6 small.
