Want ST.PATRICK GOWN-Need Help To Identify!!!

Hi! I`m looking for a st. Patrick gown that I tried on in a shop. I don`t have the style number or a pic and am hoping someone will help me identify it. A store I contacted told me it`s a discontinued model but gave no further details. I`ve emailed the designers a couple of weeks ago but have had no reply (maybe on christmas holidays?).
So here goes- the dress looks fitted from the front but from the back waist-level down opens up wider and has a train. It has a high chinese-style like collar which is open in a V at the front. The back is rather interesting as the top half is fastened with buttons and there is a drop-shaped cutout on either side of each button (making it look a bit like butterfly wings) and the lower half fastens with a normal zip. I believe the fabric was satin and it wasn`t white - don`t know if it comes in more than one colour.
If anyone out there can let me know the style number, has a picture of this gown or better still one for sale please let me know.
Thanks!!!
