This item is new, only tried on. I fell in love with it and bought it overseas several years ago. I think it's a very rare item. When I bought it, I was 160cm tall and weighed 45kg. Recently, I had my middle school daughter try it on, and it fit her perfectly too. She is 153cm tall and weighs 40kg. As you can see in the photos, there is a rubber stopper on the upper chest area to prevent it from slipping. The rubber shows no signs of deterioration. I'm hesitant to sell it, so the price is high, but I will sell it to someone who likes it. No price reduction, please.
