"MIRAGE
It’s not your imagination! Mirage has classic elegance on lock. Spun of luminous taffeta, she floats with your every movement while keeping it playful with a knotted back bow. Subtle ruching at the bodice frames the strapless neckline and low back. Springing from the natural waist, a full circle skirt with pockets sweeps into a chapel train. Shown in off-white.
Colours: Available in white and off-white.
Gown details: A strapless taffeta ballgown with knotted back bow. Soft ruching at the bodice transitions into a full circle skirt with pockets. Chapel train."
