I hope your prepared to spend a lot since the jacket costs 580 RMB ($100 USD) and only limited number of 5,000 will be on sale.
That's actually less then I would have expected, the hooded Columbia shell I wear over a fleece in the rain or snow was I recall something like 50 to 60 bucks already.
Though really I was musing idly on the item generally. Allot of anime/okatu merchandise is too cringe inducing for me to even contemplate, but this is low key enough not to be embarrassing to be seen in, but given my proportions even if I was inclined to try and acquire one (which I'm not really) it would be rather unlikely to fit well.
