The bust measures approximately 45 centimeters. It's a black dress from the brand "Diem." It's made of a summery fabric, so it's cool to wear. It's not see-through, so you can wear it on its own, which is convenient. The waist area has buttons on the right and left sides, allowing you to tie it with strings. You can tie it in the back or remove the strings altogether. This allows you to wear it without cinching the waist, creating a straight silhouette. It makes you look slimmer than usual. The knee-length makes it elegant. I cut off the tag at the neck because it was itchy. I bought it at the M I department store. No stains, tears, or odors.
