Topshop Black & White Polkadot Midi Dress with Open Back

Brand new black midi (almost maxi) dress with white polka dots from Topshop. Hasn’t been worn before. Has open back detailing. The slit has been closed but can easily remove stitching. (Having a major closet clean out as I am currently pregnant and moving across provinces post-partum, so will need to get rid of lots of gently used clothes. Please feel free to look through account for other great listings!)
