I purchased this at a local department store for about 10,000 yen. It comes with a petticoat. The knit material stretches, so it accentuates the body's lines beautifully, and I received many compliments. I think you can use it for both formal and private occasions, regardless of the TPO. I only wore it once for a few hours at a class reunion. It has been dry cleaned. [Measurements] These are amateur measurements. Please allow for some error. Length: 103cm Waist: 58cm (stretchy material) Shoulder width: 33cm The condition is good, but it is a used item. Please consider this before purchasing. I plan to compress it compactly and ship it via Yu-Packet Post. Please be aware of any folding wrinkles.
