WANTED: Maggie Sottero Low Cut Back Wedding Dress

Hi everyone! I was just wandering if maybe someone has a dress that I`m looking for. My favorite is the Maggie Sottero Lorreta, but it`s $700 and I just can`t spend over $300 on a dress. If you know of anyone or anywhere that I could purchase a dress even similar to the Loretta, please let me know....you can email me at jessicalh8@hotmail.com. Thanks so much!
Sincerely,
Jess
