This is a dress my mother owned. The tag says "free size," but most of the other dresses she owned were size S-M. Please consider this as a reference. She is about 155cm tall and her shoe size is 24cm. She is quite slender. The price is based on other sellers' listings. I'm not very familiar with the market price, so please feel free to comment if you have any requests. I am happy to add more photos or take measurements upon request in the comments. Please understand that these are amateur measurements. The narrowest part of the waist is approximately 30cm. Please consider purchasing. I plan to list more dresses. I will consider offering a discount if you purchase multiple items. Thank you for your interest.
