Trews

[IsaacW]

As i said no fishtails on Military Trews and only a seam in the inside leg, no seam on the outside.

That is very true on the currently issued trews. Historically, however, fishtail were the norm on trews. I am not sure when the switch over occurred (sometime post WWII). Anyway, main people still refer to the fishtail backs as "military style" even though the military no longer wears them as such. Basically, like many things, military fashion changes along with the rest of society.
