xD No worries~ I've been collecting reference pics for him as well, though really I haven't found a lot of great ones for his outfit so far, but for his knife, I might have a few.
could work as a reference for his first knife, as well as for some of the details used on his sash and shirt.
Since his coat and pants are really basic patterns (as was mentioned by Keita) just making your own patterns would be easiest, his coat and pants are pretty much really simple. For the pants, probably baggy pajama pants would work, and for the coat, just make a longer coat with tails that you can tie in the back. ...if that helps at all. :/
