I bought this about 15-20 years ago because I fell in love with the design at first sight, but I only wore it a few times and kept it stored in a dark place. The size is marked as ① in the 6th photo, but I believe it's equivalent to a size S. The collar is detachable, and you can change the look by tying the waist ribbon in the front or back. It looks great worn as is as a sleeveless dress, or with a thin long-sleeved shirt underneath (which is how I used to wear it), so you can wear it for a long season ☺︎ It's so cute, please consider it...! ※Immediate purchase OK ※It will be folded and shipped via Yu-Packet Post. ※Discounts are available for combined purchases and shipping with other items.
