Looking For An Elie Saab

Hello! I tried on a dress at a bridal retail store and loved it... They said it was an Elie Saab. As I was mulling over whether to buy it, they called me about selling the sample at half price, then accidentally sold it out from under me before my appointment to buy it. I was heartbroken and didn`t want to reorder it from the same store, so I have been looking around, but I can`t find any information about this dress *ANYWHERE*!

They told me that the dress was silk taffeta.
It had a ruched, asymmetrical bodice.
Strapless, did hug the upper hips but then the skirt opened up fully like an A-line below the ruching.
No lace, no ruffles, no details like that. It was a simple dress but beautifully cut.
Please let me know if you know anything about this dress, style/name, anything. Ever obliged.
