I purchased this from a shop that sells Korean clothing ꕤ*.゜ It's a long-sleeved top with a collar from Aosta ꪔ̤ It's a long-sleeved top made of a soft, stretchy, and comfortable material. I wore it by itself even in winter; it's a good thickness. Because it's a soft material, I've washed it three times, so there's a little bit of pilling, but it's still in good condition. I wore it three times under a dress. I think it's about a Japanese size 95-100. I'm selling it because my child has outgrown it, and I want to use the money to buy new, cute clothes ꕤ*.゜ It's been washed at home, so I can ship it right away. I plan to ship it in a Ziploc bag in a Yu-Packet Post box with tracking ꕤ*.゜
