This jacket was purchased over 20 years ago at Okura in Daikanyama. The size is listed as 2, but it fits like a size L (usually, Okura items in size 2 would be M). It's made of a fairly warm material, so I could get by without an outer layer until around Christmas. I'd wear a stretch fleece long-sleeved T-shirt and a white shirt underneath, and I wouldn't feel cold. I think this is an item that can be very useful in the coming season, so I hope you'll consider it. I loved it, but I haven't worn it recently and it's been in my closet, so I'm selling it to declutter. I've taken good care of it, but it's vintage, so there's a feeling of use, and there are also some pills and fuzzing, so please refrain from purchasing if you are sensitive to these things. To save on shipping costs, I will fold it when packing, so please be aware that there will be some folding wrinkles. Okura HollywoodRanchMarket Hollywood Ranch Market Seilin & Co. BLUE BLUE High!
