Designer Gown Sz 12,But Adjusts Up & Down A Few Sizes

I couldn`t decide between this dress and another one. I bought this one and quickly realized I made a mistake. There`s nothing wrong with this dress that I seen anyway. It`s a brand new Monalisa Royale by Maggie Sottero, Ivory/Pewter, size 12 and completely gorgeous.

I need to sell this so I can buy the other, I`m asking for $550, less then what stores are selling it for.

Description:One-piece, CORSET(can adjust to sizes up or down), strapless, full A-line gown with sweetheart neckline. The gown features regal embellished embroidery accented with Swarovski crystals, bugle beads, seed beads, glass beads, and sequins. Embellishments ornament the bodice and center front skirt panel. The caught-up cutaway skirt is richly decorated with motifs that also accent the caught up skirt back. The embellished chapel length train finishes the style.
