Still reading the tropes site...and apparently a common fanon 'fact' is that Edward Elric's pants are leather.
Um...'scuse me...but they're given the same color and texture treatment as the shirt/tunic he wears...and it's obviously a military uniform.
Which are commonly thick cotton/wool/you know....some sort of fiber-based material.
Where did they get this stuff?
Yeah, I'm with Vic on this one: Edward's gotta be smarter than that (also, underage fetish, anyone? ew. XD )
(ETA: And don't any of you start up with that whole 'yeah, but we know what your favorite characters commonly are age-wise...I claim
This as my self defense...*cough, shifty eyes*)
