This is from the mysa closet collaboration with Rina Tanaka, purchased online from Shimamura this summer. It's a navy knit with super cute gold buttons. I usually wear a size L, and I bought a size L, but I was a little concerned that it emphasized my chest, so I'm letting it go while it's still in good condition. I've worn it twice and home-cleaned it. It's still wearable, so I'm selling it to someone who was looking for it, and who understands that it's used. Price reduced! Please refrain from negotiating.
