Hi Adam,
If you're going to get one kimono, my advice would be an unlined
synthetic one, which you'll be able to wear throughout the year to
practice, and can be dressed up for formal occasions. I would stick
with a dark blue, black or dark brown. Ichirioya (http://
www.ichiroya.com/index.php) sometimes has kimono in large sizes, and I
believe they will custom make synthetic kimono as well. You could
also try Rakuten. You're probably looking at the $300 range.
An alternative would be to try to find someone near you who knows how
to make kimono. You may find that this isn't so much cheaper than
having something custom-made online or in Japan, though, so another
possibility is to learn how to make them yourself. Making unlined
men's kimonos is not actually that difficult, especially if you can
find someone to teach you. More than likely you'll have to use
Western fabric, because if you're taller or heavier than the average
Japanese man, regular kimono fabric will not be wide enough to make a
kimono that fits you (kimono fabric comes in a standard size which is
mostly about 15" wide. In my case, for instance, my sleeves need to
be 17" wide in order to fall to the wrist, which means that, allowing
for hems, 15" wide fabric is at least 4" too narrow). Using Western
fabric, sewing a man's kimono consists of 5 main steps: 1): cut 7
rectangles, for the body, sleeves, overlap (okumi) and collar; 2): sew
in the back seam; 3): attach the sleeves and sew the sides of the
kimono; 4): attach the okumi panels; 5): attach the collar and collar
cover, and sew all the hems. Most of the sewing can be done by
machine, making it quite fast. There are two hard parts: attaching
the collar, and hand-sewing the visible hems. The first is just a
tricky process, while the second is not actually particularly hard,
it's just very time-consuming. I would suggest taking the finished
measurements from a kimono you already have rather than relying on
methods in books, which can be unnecessarily complicated and quite
misleading. Check out the Immortal Geisha forums (http://
www.immortalgeisha.com/ig_bb/index.php) for lots of discussion on how
to make kimono.
