I have learned quite a bit about traditional Japanese attire as well, but like MomoDesu, I am guilty of laziness as well. I suppose if I was planning to write on a more professional level, I would do more research and attempt to be more specific and exact in my clothing descriptions, but as I do not foresee such a thing, I think my current knowledge should be sufficient.
On the other hand, I really appreciate the link S.A.M!! I can really use some of those patterns as a reference in future drawings!
