Wedding Dress Needed

Looking for great dress size 16-20. Bust 42-44, waist 30-32. I`m pretty busty. I`m looking for a designer cut, great fabric. I love Maggie Sottero, Justina McCaffrey, Ian Stuart, Keveza, Fenoli, Ristarose. Basically, I`m looking for a good soul who can afford to sell me her dress at a fraction of what she paid. If you know of a great seamstress, I`ll take the contact. Thanks!
