i tried the new bow bag today.. and the crossbody strap is definitely too short!!
if anyone is interested the price is 1130/1160CDN (cant remember which)
i saw some original bow bags (aplenty) in london selfridges. you can get them to ship it over if you really want.
I did see the beige-y one and the sort of mauve-ish and black bow satchels... that was about 2 weeks ago though! However I think you might be lucky and they might still be there. Btw there's only one selfridges in london. www.selfridges.com ask for the miumiu accessories concession.
