Straight sheath dress with a zipper

A beautiful straight-cut midi sheath dress with a unique feature - a zipper running the entire length of the back. It creates a nice silhouette. Cornflower blue color. Knitted collar. Velvet/velour to the touch. I don't remember how I got this dress, but it's now too small, so I'm looking for a new owner. Very good condition. Size 42 on the label, fits S/M: Bust - ~45 x 2 cm (slightly stretches) Waist - 33 x 2 cm Length - 102 cm Sleeve - 13 x 2 cm Sleeve length - 46 x 2 cm
