I'm not sure if this is in the right category, so forgive me.
My friend and I are thinking of going as Rin and Len Kagamine(Vocaloid). I have pretty much all the clothing down(shirt, tie, shorts, leg warmers, arm warmers, etc). But the belt is something I don't know how to make exactly: http://farm3.static.flickr.com/2599/...aa57da77aa.jpg
I'm not sure how I can make some sort of yellow belt with those orange(or brown) triangles. What's the best way to do this?
