Looking at that picture makes me realise how much more I like spread and semi-spread collars at the moment.
Also, CT has a sale on shirts atm (don't they always?). ctshirts.com/aust2
edit: interesting, only works with .com, not .com.au
I know that CT are not highly thought of and their not top tier but I bough a causal one recently in a navy blue button down which I am getting good wear out of. i still have a couple of business shirts of theirs I bought years ago which I still wear.
