Thank you for viewing. This is the BIG-T from anonenone's Dekasugi Kare-kun (Oversized Boyfriend) series. The color is black, and it's sold out on the official website. I am also listing the white version from the same series. It's 6000 yen if you buy both. I bought this as loungewear but never had the chance to wear it, so I'm selling it. It's new, unopened, and with tags. Instant purchase is welcome.
