I may have shared my summer take on the 10×10 challenge last week, but given that we’re currently in the throes of winter down under, I wanted to give you a good look at what I actually wore for the winter 10×10 challenge. I should probably mention upfront that Sydney winters are more mild than most. While it might dip down to lows of 4 or 5 deg C in the evening, the coldest I’ve seen the thermostat get during the day is a cool 15 deg C – so if the sun is shining, you can generally get away…
