I got the DBSS coat from this store (link uses the Google cache since the store deleted the web page after it sold out)....http://18.104.22.168/search?q=cache...tone/10004692/
You can see the measurements near the bottom of the page. The size 1 is 45 cm pit-to-pit and fits about like a US men's XS. Though I have never seen a store carrying the jacket in any size other than the size 1. So if you need a bigger size, good luck!
I find myself liking a lot of Diet Butcher's FW09 collection too, but I'm not overly excited by the SS09 collection pictures they recently released. The new stuff looks very Julius-esque with drapey shirts, etc. However, maybe I'll change my mind when I see them being worn by a model as opposed to simply pictured on a hanger.
