Armor is the main issue here, IMO. Oriental armor has the AMAZING Kikko Armor (a +5 AC medium armor with a max DEX of +4 for only 30 gp!) and a probably broken light armor that has neither check penalty, arcane spell failure nor max DEX, the infamous-3gp-Haramaki. Tatami-do is also a cheaper fullplate (provided your dex modifier is +3) for 1.000gp.
Keep these things in mind when adjudicating. I let my players purchase them seamlessly with regular armors, but some DMs might object to that.
