Preen by Thornton Bregazzi collection gathered maxi Runway Dress small I could not find exact photo for this, so the model is for style idea/reference. A very unique and loved dress. Silk contrast with cotton stretchy black top, adjustable belt loop fabric around the waist , long flowy white/off white silk maxi skirt. Overall good condition, but there is some water damage to the bottom of the dress shown with arrow in last photos on the underneath back side of the dress. I don't know any more about this dress if you do let me know! Approx. measurements 55" LONG, 18" PIT TO PIT, 17" ACROSS THE WAIST (CAN BE WORN WITH A BELT IN THE FABRIC CENTERPIECE TO TIGHTEN WAIST) 9.5" WIDE ARM OPENINGS. IT ALSO BUTTONS IN THE BACK TOP NECK.
