So a "naked" jacket with a LG is in order?

From my googling over the past year or so there seems to be more canadian than British jackets, and sometimes some Polemic about the color in these canadian jackets (which are apparently cheaper than the British ones... what would you advise a "i just need one classic piece" kinda guy, as opposed to someone who needs all the variations?
