This is a knit set. I'm selling it because the skirt length is too short for me, as I am 166cm tall. It doesn't have built-in shorts, so it can be worn by people of any height. The fabric is very thick, so you can wear it warmly even in mid-winter. I'm using photos from Yurara-chan, who is 153cm tall, from her YouTube video. I've worn it once, and I've washed it after it arrived and after trying it on. It's knit, so it has a little bit of wear and tear. Please refrain from purchasing if you are concerned.
