NEW size 18/20 5x UK, Beautiful Black and Magenta strap long maxi dress

NEW size 18/20 5x UK, Beautiful Black and Magenta strap long maxi dress No tags, I ordered it from the internet and the sizing was not a US 5x that I needed to order. They had it in the bag and no tags but you can see it’s new and never been tried on. It’s really pretty. Note- This is not a US 5x. It’s really a size 18/20 in US sizing
