I bought this at Kapital in Tokyo. I don't know if it was a one off couture or a catalogue item, but they certainly didn't have more than the one Fabric is extremely soft yet durable, it feels similar to moleskin fabric. The weft and thread are a very nice contrasting purple. Impeccable tailoring. Thought it's labeled as an XL and Japanese size 4, please note that Japanese XL is not an American XL. I wear a size L in most shirts.
