This is a RYOKO KIKUCHI formal dress (mourning dress) purchased a few years ago from the formal wear section of AEON. It's a black one-piece suit with a jacket, featuring balloon sleeves and a waist ribbon. The back zipper size is 7. The dress length is approximately 98cm. I'm selling it because I've worn it three times and can no longer wear it due to a change in size. It was dry-cleaned at a dry cleaner's the last time I wore it. I discarded the cleaning tag when I was going to wear it because I had plans to wear it. There is a faint, rubbed-like white stain on the back of the dress. It's in a position that will be covered by the jacket, and it might come out if you have it cleaned again, but I haven't tried, so please consider this before purchasing. - Color: Black - Style: One-piece suit - Design: With jacket - Sleeve style: Balloon sleeves - Features: With waist ribbon - Material: Polyester blend RYOKO KIKUCHI Thank you for looking.
