Nissen Callarus Mourning Wear / Formal Wear - Made in Japan Fabric - Blouse and Pants, L Size

Thank you for looking.
Purchased in September 2024.
I was looking for a stylish pantsuit mourning outfit on Amazon for the first Obon service. It had high ratings, was washable at home, wrinkle-resistant, and had an elastic waistband.
The long blouse also stylishly covered my figure.
When it arrived, it exceeded my expectations and I was very satisfied.
At the time, I thought it might be a little small, but when I tried it on the other day, it felt completely too small, so I am selling it.
Worn 3-4 times.
Washed in a home washing machine after wearing (there are fold wrinkles on the lining).

...
It will be folded compactly and shipped anonymously, so please understand that there will be fold wrinkles.
Although it has been worn only a few times, please understand that it is a used item and refrain from purchasing if you are looking for perfection.
I am not considering price reductions for the time being.

For your reference,
I purchased it on Amazon for 15,590 yen at the time, but when I checked the price now, the L size is 19,690 yen without a coupon.
