Black strapless cocktail dress

Sexy (but not stressful to wear!) black satiny cocktail dress. Flattering pleat detail on the bodice (the pleats have a layer underneath that is right across the bodice so there's no risk of gape). 15 inches at the bust, 19 at the widest point of the hips, 32 from top of bodice to hem. 4 inch slit at the back. Boning at the sides keeps the bodice in place. Made of a poly/cotton blend that feels like a heavy satin. Hits just below the knee on someone 5'8. Label says size 12 but it was made in Australia and fits a size 6/8 in Canada.
