Technically it is a 50% off sale but PriceHipster has these hovering around the $499 mark at Myer (sale is with R&G direct). There are heaps more jackets and other clothing at 50% off instore and online. I tried a few jackets and polos on yesterday and they seem pretty good quality; internet forums generally agree (nb 6 year old thread).
My recommendations: Jacket for cold wet conditions: https://www.roddandgunn.com/au/clothing/sale/jackets/coronet…
It has a removable vest inside so a bit of a 2 in 1.
Longer coat as they are in fashion at the moment: https://www.roddandgunn.com/au/clothing/sale/jackets/newstea…
or look at the Christchurch coat if you are more conservative in colouring. There are other longer coats but at a lesser discount, e.g. Rocky Bay.
Casual: https://www.roddandgunn.com/au/clothing/sale/jackets/maymorn… it's a bomber style so don't bother if you have a longer torso than normal.
If you have too much money: https://www.roddandgunn.com/au/clothing/jackets/hoffmans-jac… I tried this on and damn it was nice; lamb skin tanned in France.
The "Sports Fit" polos were good for tall slim bodies, a bit expensive but hopefully will last longer than a Best & Less polo. A lot of their rugby polos are on sale too.
Not that stylish to be honest. But this kind of thing is subjective.
