I've lived for over a decade in both cities and I have to say that Sydney's the place that likes wearing black turtle neck skivvies.
I haven't seen it once here.
We have our share of tossers like every city but they don't wear that, although I'm sure there'll be someone who pops up wearing the same or similar at some stage.
Black balaclavas are more the style down there these days
