This is a PLST jacket and pants set. I purchased them over 4 years ago for about 40,000 yen in total. The jacket is size S. The pants are both size XS and are different styles. One pair is slim tapered pants, and the other is straight-leg pants. At the time, the sizes ran large, so I bought them one size smaller than usual. (I was about 158cm tall and weighed less than 50kg at the time.) I wore them less than 20 times after purchase, and they have been stored at home since then. There are no noticeable stains. They are washable and wrinkle-resistant, so they were very useful. They can be used for business, as well as ceremonies and formal occasions. I am not considering selling them separately. I want to get rid of them, so I prioritize buyers who will purchase the set. Please negotiate the price in the comments.
