I am rebuilding this gown. It was made with a separate bodice and skirt and the skirt is full circle. Neither the bodice nor the sleeves have ever been quite right - the bodice laced up on one side and the sleeves are too tight at the forearm and have funny kind of latches as closures.
Anyway I have taken it apart and cut enough out of the skirt to make a completely new bodice and remade the sleeves. Of course I can't do anything about it being made as separate skirt and bodice but the belt hides that and the velvet is too gorgeous to throw away.
