This was purchased in Thailand. The sleeves are lantern-shaped and cute ^_^ The fabric is thin, so it's very cool to wear. I've worn it a few times. There are a few loose threads, possibly due to the overseas specifications, so please check the photos (photo 7). There's no tag, but I think the size is about a Japanese M size. (I've labeled it M because the size is about the same as the M size I usually wear.) I've listed the detailed measurements below, so please check them♪ ●Size Shoulder width: about 38cm Body width: about 49cm Sleeve length: about 16cm Length: about 52cm Measurements are taken flat. Please note that there may be slight variations due to amateur measurements m(_ _)m
