Long Embroidered Silk Dress

Just bought secondhand, just didn't realize that a size 38 would be too big on me (usually a 4). It is at least equivalent to a 6, and maybe an 8 if you aren't real curvy. Lot of excess around the waist for a 4, but still looks ok. Not sure if the knot-buttons will hold well, but they can probably be adjusted or replaced with clasps. There's a little snap to keep it up around the bust that seems fine. Only tried on so can't really say.
