I thought I should size up since I have a large chest, but it was a mistake. The blazer turned out to be a very baggy boyfriend fit. There is lining inside. It's quite thin and there's no shoulder pads. I'm only 159 cm so the blazer lands on my hips.
Shipping was very speedy, only 11 days. I bought L for 72cm waist. The skirt is thinner than I expected, and the color is lighter. The model's photos are from korean brand Dejou, but this skirt has a different tag, so I believe this is a replica.
