This outfit was purchased at the designer's trunk show 27 years ago, when my daughter was 13.  It was custom fit for her so the size is NOT standard! I paid $750.00 for it and she wore it once.  The neck is slightly soiled and needs to be dry cleaned.  It is exquisitely made.  Both the jacket and dress are lined and the halter dress has stays.  Both jacket and dress are studded with rosettes made from a different fabric which I cannot identify.  The dress has a dropped waist and zips up.  The jacket has no closure.
