Wanted: Romona Keveza Strapless

Wanted: Romona Keveza Strapless, cumberband around waist, organza bottom, very light. Diamond White. Not sure what the style number is, I tried it on at bridal salon and it is on the romonakeveza.com site under runway 2, picture 12. Size 8 preferred. Retailed for $2800, but looking to spend less either for the dress gently worn or for a dress like this without the "Romona Keveza" label. Any suggestions? Wedding date is Oct. 15. Thank you.
