Looks great. I love how you use the suspender.
JGSDF often uses suspender for their training exersize.
As for the BDU, if you can read Japanese, you can also get a nice one from this website,

Some of them are made out of 65% polyester and 35% cotton.
However they made it in a way it is waterproof on the outside and sweat absorbant in the inside. Not to mention, even when comparing cloths that uses the same materials, this cloth is specifically designed to dry 6-8 times faster than usual so if you sweat a lot, this may be ideal BDU for you.
