Hello, I would like to give you information about the shortness of our Green Long Strap Basic Dress MG1852 model depending on your height. The length of our product is about 120-125cm, including the sling. For a user of 180 cm in height, this dress could be a point above the knee (short about 10-15 cm). So, it may not create a full long dress effect; it would look more like a midi or short dress. Please let me know if you would like more help with detailed measurements or different size options. I am happy to assist you in finding the best option for you. Best regards, Deniz Madmext Team
